Title:
DUAL POLARIZED WAVE TRANSMISSION/RECEPTION ANTENNA
Document Type and Number:
WIPO Patent Application WO/2018/180877
Kind Code:
A1
Abstract:
Provided is a dual polarized wave transmission/reception antenna having a simplified configuration. The dual polarized wave transmission/reception antenna uses, among a dipole antenna, an inverted-F antenna, and an inverted-L antenna, any two antennas the resonance frequencies of which are controlled to be substantially equal to each other, and open-end sides of the two antennas are arranged so as to be orthogonal to each other at a prescribed distance. An EM power feeding unit is arranged so as to face each of the open-end sides with a prescribed interval. A power feeding line is electrically connected to the EM power feeding unit. Thus, according to the dual polarized wave transmission/reception antenna of the present embodiment, one-point electromagnetic power feeding is carried out from respective open-end sides of two linear antennas which are orthogonal to each other and the resonance frequencies of which are substantially equal to each other, whereby a power feeding unit and a high-frequency circuit can be simplified, and a vertically polarized wave and a horizontally polarized wave can be transmitted/received with a simpler configuration. As a result of using an inverted-F antenna or an inverted-L antenna, the dual polarized wave transmission/reception antenna can be downsized, and further, the center portion of a ground conductor thereof can be cut off or an electronic circuit can be provided thereto.
