The disclosure relates generally to information handling systems, and in particular to maintaining a coupling gap using an antenna carrier in an information handling system.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
In one embodiment, a disclosed method for maintaining a coupling gap between a coupling element and a radiating element using an antenna carrier in an information handling system includes: applying, by one or more springs disposed on an inner surface of the antenna carrier, a first lateral force on the antenna carrier; causing, by the first lateral force, the antenna carrier to translate outwardly toward an edge of a mounting surface, the antenna carrier slidably coupled to the mounting surface; receiving, by one or more standoffs disposed on an outer surface of the antenna carrier, a second lateral force from an inside surface of a device cover of the information handling system; causing, by the second lateral force, the antenna carrier to translate inwardly away from the edge of the mounting surface; and causing, by the first lateral force and the second lateral force, the standoffs to maintain the coupling gap between the coupling element and the radiating element.
In one or more of the disclosed embodiments, the method further includes: transmitting, by the coupling element, an antenna signal across the coupling gap between the coupling element and the radiating element; and radiating, by the radiating element, the antenna signal outwardly away from the information handling system.
In one or more of the disclosed embodiments, the method further includes: receiving, by a compressible material disposed on a longitudinal surface of the antenna carrier, a first longitudinal force from the inside surface of the device cover; causing, by the first longitudinal force, a compression in the compressible material; and causing, by the compression of the compressible material, the antenna carrier to apply a second longitudinal force on the mounting surface to secure the antenna carrier in a longitudinal position.
In one or more of the disclosed embodiments, the antenna carrier is slidably coupled to the mounting surface by two or more shank screws disposed on opposite ends of the antenna carrier.
In one or more of the disclosed embodiments, the coupling element is disposed on the outer surface of the antenna carrier using a Laser Direct Structuring (LDS) process.
In one or more of the disclosed embodiments, the coupling gap between the coupling element and the radiating element is 0.2 to 1.2 millimeters (mm).
In one or more of the disclosed embodiments, the first lateral force and the second lateral force are equal in magnitude causing the antenna carrier to be in a stable equilibrium.
In one or more of the disclosed embodiments, the radiating element comprises a metal portion of the device cover.
The details of one or more embodiments of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other potential features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

Network interface 125 may enable information handling system 100 to communicate over network 150 using a suitable transmission protocol and/or standard, including, but not limited to, transmission protocols and/or standards enumerated below with respect to the discussion of network 150. Network 150 may be a public network or a private (e.g. corporate) network. The network may be implemented as, or may be a part of, a storage area network (SAN), personal area network (PAN), local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a wireless local area network (WLAN), a virtual private network (VPN), an intranet, the Internet or another appropriate architecture or system that facilitates the communication of signals, data and/or messages (generally referred to as data). Network interface 125 may enable wired and/or wireless communications (e.g., NFC or Bluetooth) to and/or from information handling system 100.
In particular embodiments, network 150 may include one or more routers for routing data between client information handling systems 100 and server information handling systems 100.

In one embodiment, device cover 140 may be a suitable system, apparatus, or device operable to house one or more components of information handling system 100. In particular, device cover 140 may be comprised of a rigid material (e.g., aluminum) and/or semi-rigid material (e.g., plastic) operable to provide a housing for one or more components within information handling system 100. In one embodiment, device cover 140 may be or include a bottom cover, or “D cover,” for information handling system 100. In other embodiments, device cover 140 may be or include a top cover, or “A cover,” and/or any other cover or shell suitable for housing one or more components of information handling system 100. In the embodiment illustrated in
In one embodiment, radiating element 145 may be a suitable system, apparatus, or device operable to radiate, or otherwise transmit, an antenna signal transmitted by coupling element 135. In particular, radiating element 145 may be or include a passive element comprised of a rigid material (e.g., aluminum) of device cover 140 operable to receive an antenna signal transmitted by coupling element 135 across a coupling gap (e.g., coupling gap 320 shown in
In one embodiment, coupling element 135 may be a suitable system, apparatus, or device operable to radiate, or otherwise transmit, energy. Specifically, coupling element 135 may be or include an antenna operable to radiate energy, or an “antenna signal,” in the form of electromagnetic waves. That is, coupling element 135 may receive electrical signals (e.g., electric current) from one or more components of information handling system 100 and may transmit an antenna signal across a coupling gap between coupling element 135 and radiating element 145 that conveys the electrical signals received by coupling element 135. In one embodiment, coupling element 135 may be or include one or more traces (e.g., a metal additive that forms a micro-rough track) comprising an antenna that may be written, or otherwise structured, onto a thermoplastic material doped with non-conductive metallic inorganic compounds using a Laser Direct Structuring (LDS) process. In another embodiment, coupling element 135 may be formed using flexible printing and/or metal stamping processes. In other embodiments, coupling element 135 may be or include a short dipole antenna, a dipole antenna, a slot antenna, and/or any other type of antenna suitable for transmitting energy. Coupling element 135 is described in further detail with respect to
In one embodiment, antenna carrier 130 may be a suitable system, apparatus, or device operable to maintain a coupling gap between coupling element 135 and radiating element 145. In particular, antenna carrier 130 may be or include an antenna housing comprised of a semi-rigid material (e.g., plastic, thermoplastic, and the like) operable to position, or otherwise orient, coupling element 135 at an immutable, or absolute, distance away from radiating element 145 to ensure optimal coupling (i.e., matched impedances). Conventionally, antennas (e.g., WLAN antennas) used to support wireless fidelity (Wi-Fi) connectivity in information handling systems may require bucket housings having lengthy (e.g., 45 millimeters) slots within device covers (e.g., D covers). However, these lengthy slots used to house conventional antennas may severely limit the number of I/O ports and/or speakers made available to users, thereby decreasing overall user experience. Further, such conventional systems may lack internal structures or systems required for tolerance control with respect to coupling gaps between the conventional antennas and receivers, thereby severely limiting overall antenna performance (e.g., 7 GHz performance).
In contrast, antenna carrier 130 may provide an antenna housing for coupling element 135 that allows a decreased antenna length (e.g., 23 millimeters) while providing an immutable, or absolute, coupling gap (e.g., an absolute coupling gap of 0.2 to 1.2 millimeters) to ensure consistent tolerance control within information handling system 100. This coupling gap between coupling element 135 and radiating element 145 is immutable, or absolute, in that antenna carrier 130 may be wedged securely into position (e.g., by a manufacturer) such that the position of antenna carrier 130, and the coupling element 135 thereon, within information handling system 100 may not be perturbed, or jarred, despite changes in orientation of information handling system 100, thereby increasing overall user experience. Antenna carrier 130 is described in greater detail with respect to
In one embodiment, compressible material 200 may be a suitable system, apparatus, or device operable to cushion and secure antenna carrier 130 in a longitudinal position within information handling system 100. As shown in
In one embodiment, each standoff 220 (collectively referred to herein as “standoffs 220) may be a suitable system, apparatus, or device operable to maintain a coupling gap between coupling element 135 and radiating element 145. In particular, each standoff 220 may be or include a standoff or spacer comprised of a semi-rigid material (e.g., plastic, thermoplastic, and the like) operable to establish and maintain the coupling gap between coupling element 135 and radiating element 145 to ensure optimal coupling (i.e., matched impedances). In the embodiment illustrated in
In one embodiment, each shank screw 210 (collectively referred to herein as “shank screws 210”) may be a suitable system, apparatus, or device operable to slidably couple antenna carrier 130 to a mounting surface (e.g., e.g., mounting surface 310 shown in
In one embodiment, each spring 230 (collectively referred to herein as “springs 230”) may be a suitable system, apparatus, or device operable to apply a lateral force used, in part, to secure antenna carrier 130 in a lateral position within information handling system 100. In the embodiment illustrated in
In one embodiment, compressible material 200 may receive a longitudinal force from the inside surface of device cover 140. This is shown in
In addition to the longitudinal force 330 described above, springs 230 may apply a lateral force on antenna carrier 130. In particular, springs 230 may apply a lateral force 340 upon antenna carrier 130 causing antenna carrier 130 to translate (e.g., via shank screws 210 shown in
Method 400 may begin at steps 410 and 420, where one or more springs disposed on an inner surface of the antenna carrier may apply a first lateral force on the antenna carrier causing the antenna carrier to translate outwardly toward an edge of a mounting surface. The antenna carrier may be slidably coupled to the mounting surface. For example, springs 230 may apply a lateral force 340 upon antenna carrier 130 causing antenna carrier 130 to translate outwardly toward the edge of mounting surface 310 as described above with respect to
