Abstract

The invention discloses a wideband high-gain Fabry-Perot resonator antenna which comprises a metal reflection board, a feed waveguide, a layer of first medium plate, a layer of second medium plate and a layer of third medium plate. The first medium plate, the second medium plate and the third medium plate are hung right above the metal reflection board. A feed crack port is formed in the metal reflection board, and a waveguide port of the feed waveguide exposes out of the feed crack port. The first medium plate, the second medium plate and the third medium plate with different dielectric constants are adopted, an Fabry-Perot resonator is formed by the metal reflection board and the medium plates, a small antenna is formed by the feed waveguide and the feed crack mouth; when the small feed antenna located on the metal floor inside the resonator feeds, high gain of resonant frequency of the resonator is produced in the normal direction of the antenna. A millimeter-wave working bandwidth larger than 34% (28.4GFz-40GHz above) is realized under the condition of S11<-10dB, and in-band gain is 16-18dBi. The wideband high-gain Fabry-Perot resonator antenna has the advantages of being high in gain, wide in band, small in size, simple in structure and low in cost; besides, high use value and promotional value are achieved.

Description

technical field [0001] The invention relates to the technical field of antenna engineering, in particular to a novel wide-band high-gain Fabry-Perot resonator antenna (Fabry-Perot resonator antenna), which can be used in microwave / millimeter wave band communication equipment such as mobile communication and satellite. Background technique [0002] With the rapid development of radio communication technology, the communication system becomes more and more miniaturized, integrated and high-performance. Broadband, high gain, miniaturization, and ease of integration are the hallmarks of modern high-gain antenna designs. Traditional high-gain antennas mainly include reflector antennas and array antennas. The former antenna has a large volume, while the latter has a complex design and requires a complex feed network, and the cost of both types of antennas is relatively high. In recent years, with the development of material technology and the improvement of analysis methods, man...
