The disclosure relates to a diversity antenna and an electronic device including the same.
A monopole antenna has a simple structure and an omni-directional radiation characteristic, and accordingly, the monopole antenna can be used in a small or mobile electronic device.
Antenna diversity means that a plurality of antennas (e.g., a plurality of monopole antennas) is used in one electronic device for enhancing transmitting and receiving performance of the electronic device. A diversity antenna refers to an antenna that is used for antenna diversity.
The above description has been possessed or acquired by the inventor(s) in the course of conceiving the present disclosure and is not necessarily an art publicly known before the present application is filed.
When using a plurality of antennas for the antenna diversity, each of the plurality of antennas may not have an omni-directional radiation characteristic due to interference between the plurality of antennas.
In various example embodiments, the omni-directional radiation characteristic may be obtained by arranging the plurality of antennas coaxially and locating a power supply line inside a radiation element.
In various example embodiments, a reference point may be set accurately by arranging the plurality of antennas coaxially, and therefore, it is possible to increase accuracy when searching for a location of an object by using a radio frequency (RF).
However, the technical problems are not limited to the technical problems described above and other technical problems may exist.
According to an aspect, there is provided a diversity antenna including a plurality of radiation elements having a tubular shape with apertured upper and lower portions, and a connection plate configured to connect the plurality of radiation elements to each other, in which the plurality of radiation elements is arranged in a vertical direction coaxially, and the connection plate includes an aperture configured to allow a power supply line to pass through.
The tubular shape may include a cylindrical shape.
The diversity antenna may further include a printed circuit board (PCB) configured to connect the power supply line to the plurality of radiation elements.
The PCB may be disposed on an upper surface of the connection plate.
The diversity antenna may further include an earth plate for earthing of the diversity antenna, and the earth plate may be disposed on a lower surface of the connection plate.
The diversity antenna may further include a connector configured to connect the power supply line to the PCB, and the connector may be formed to penetrate the connection plate and the earth plate.
The diversity antenna may further include a lower plate coupled to a lower aperture of a first radiation element that is disposed at a lowermost end among the plurality of radiation elements; and an upper plate coupled to an upper aperture of a second radiation element that is disposed at an uppermost end among the plurality of radiation elements, and the lower plate may include an aperture configured to allow the power supply to pass through.
The diversity antenna may further include a second power supply line configured to connect, to the plurality of radiation elements, a first power supply line that is connected to an electronic device, and the second power supply line may be disposed inside the plurality of radiation elements.
The diversity antenna may further include a PCB configured to connect the second power supply line to the plurality of radiation elements.
The PCB may be disposed on an upper surface of the connection plate.
The diversity antenna may further include an earth plate for earthing of the diversity antenna, and the earth plate may be disposed on a lower surface of the connection plate.
The diversity antenna may further include a first connector configured to connect the second power supply line to the PCB, and the first connector may be formed to penetrate the connection plate and the earth plate.
The diversity antenna may further include a lower plate coupled to a lower aperture of a first radiation element that is disposed at a lowermost end among the plurality of radiation elements, an upper plate coupled to an upper aperture of a second radiation element that is disposed at an uppermost end among the plurality of radiation elements, and a second connector configured to connect the first power supply line to the second power supply line, and the second connector may be formed to penetrate the lower plate.
According to another aspect, there is provided an electronic device including: a housing, and a diversity antenna that is disposed outside the housing, in which the diversity antenna includes: a plurality of radiation elements having a tubular shape with apertured upper and lower portion, and a connection plate configured to connect the plurality of radiation elements to each other, the plurality of radiation elements is arranged in a vertical direction coaxially, and the connection plate includes an aperture configured to allow a power supply line to pass through.
These and/or other aspects, features, and advantages of the invention will become apparent and more readily appreciated from the following description of example embodiments, taken in conjunction with the accompanying drawings of which:
The following structural or functional descriptions of example embodiments described herein are merely intended for the purpose of describing the example embodiments described herein and may be implemented in various forms. Therefore, the example embodiments are not construed as limited to the disclosure and should be understood to include all changes, equivalents, and replacements within the idea and the technical scope of the disclosure.
