The disclosure relates to an antenna module and an electronic device including the same.
With the development of mobile communication technology, electronic devices having at least one antenna are widely disseminated. Electronic devices may transmit and/or receive radio frequency (RF) signals including a voice signal or data (e.g., message, image, video, music file, or game) using an antenna.
An antenna may simultaneously transmit and receive signals belonging to different frequency bands by using a plurality of frequency bands. Electronic devices may provide a service of a global communication band by using signals belonging to different frequency bands. For example, electronic devices may perform communication (e.g., GPS, legacy, WiFi1) using a signal belonging to a low frequency band (LB) and/or communication (e.g., WiFi2) using a high frequency band (HB).
Meanwhile, electronic devices may transmit and receive signals using an antenna module including a plurality of components (e.g., patch antenna) in a housing. For example, a plurality of patch antennas included in an antenna module may be electrically connected to one portion of a printed circuit board so as to be fed. A patch antenna may be referred to as an antenna element that radiates or receives an RF signal of a specified frequency band (e.g., ultra-wide band (UWB)). Electronic devices may transmit and/or receive signals belonging to various frequency bands by using the above antenna module.
Electronic devices may include a plurality of antennas for transmitting and/or receiving signals of different frequency bands. Electronic devices may have a physical limitation in efficiently securing a frequency band in which a plurality of antennas transmit and receive. For example, a mounting space of electronic devices is physically limited, but components included in an antenna module may require a larger mounting space to efficiently perform a radiation operation.
Because the mounting space of electronic devices is limited, it may be difficult to secure an enough height of an antenna structure. For example, a patch antenna included in an antenna structure requires a specified height (or thickness) so as to exhibit optimum radiation efficiency. However, due to the above-mentioned limitation in a mounting space, particularly the limitation in height, it is difficult to implement an optimum lamination structure.
According to an aspect of the disclosure, an electronic device includes: a housing including: a first plate oriented in a first direction, a second plate oriented in a second direction opposite to the first direction, and a side member surrounding a space between the first plate and the second plate; a support member disposed in the space between the first plate and the second plate; a printed circuit board disposed on one surface of the support member and including a wireless communication circuit; an antenna disposed on the printed circuit board; and a processor operatively connected to the printed circuit board and the antenna, wherein the antenna includes: a first conductive patch disposed at a first layer and electrically connected to a first transmission line; a second conductive patch configured to be spaced apart from the first conductive patch at the first layer and electrically connected to a second transmission line; a third conductive patch configured to be spaced apart from the first conductive patch and the second conductive patch at the first layer, and electrically connected to a third transmission line; and a shielding member disposed at a second layer, and wherein the processor is configured to receive a wireless signal of a specified band by feeding the first conductive patch, the second conductive patch, and the third conductive patch using the wireless communication circuit.
