Abstract

The invention is concerned with a kind of a kind of coplanar wave-guide feeding broad-band entelechy millimeter wave plane gap antenna, belonging to communication technology field, relating to coplanar wave-guide feeding line, circular radiation gap, micro-disturbing short circuit modulation spur track, center metal circular pasting piece, outside earth-plate and micro-wave medium floor. The coplanar wave-guide feeding line, circular radiation gap, micro-disturbing short circuit modulation spur track, center metal circular pasting piece and outside earth-plate are on one plane and prepared on the micro-wave medium floor. The coplanar wave-guide feeding line is under the circular radiation gap and connects with the center metal circular pasting piece on portrait directly. The micro-disturbing short circuit modulation spur track is to the right of level direction of circular radiation gap and connects with outside earth-plate. This invention has easy adjustment size and matches with impedance, the feeding line is on one plane with radiation unit for the demand of entelechy and broad band.

Description

technical field [0001] The invention relates to an antenna in the technical field of communication, in particular to a coplanar waveguide fed broadband circularly polarized millimeter wave planar slot antenna. Background technique [0002] With the development of satellite communications and the increasingly crowded radio channels, radio technology is developing towards shorter and shorter millimeter waves and submillimeter waves. Millimeter wave has the characteristics of extremely wide bandwidth, high resolution, and all-weather operation. The size of millimeter wave components is small, and it is easier to miniaturize and integrate. Therefore, millimeter wave technology has a wide range of applications in military, communication, security and other fields. But traditional antennas have encountered new difficulties in the millimeter wave band. First of all, with the increase of frequency, the requirements for processing accuracy are getting higher and higher. Traditional...
