Embodiment 1
[0048] The size parameters such as the cylindrical through hole and the phase alignment cylindrical through hole in the selected annular honeycomb panel structure of the embodiment of the present invention are as follows:
[0049] In this embodiment 1, the first feed source 6 adopts a horn antenna working at 12-18GHz, which is installed on the axial focal length position of the porous honeycomb antenna, the axial focal length of the porous honeycomb plate antenna: L=140mm, the porous plate honeycomb The plate is made of a circular dielectric plate with a radius of 72mm, a thickness of 15mm, and a dielectric constant of 4.4. Within every 8mm, two cylindrical through holes with a distance of a=4mm and a radius of r are set. The radius is from the center of the circle to the edge. The radial direction is: 0.5mm, 1mm, 1.6mm, through the sequentially changing cylindrical through holes, the phase of the incident wave is adjusted, and the gain and directivity of the antenna in the ver...

Description
technical field [0001] The invention belongs to the technical field of communication, and relates to a highly directional bidirectional radiation porous honeycomb plate antenna, in particular to a porous honeycomb plate antenna capable of simultaneous vertical radiation and horizontal radiation, which can be applied to the technical field of satellite communication. technical background [0002] Traditional two-way radiation uses two unidirectional radiation antennas arranged back-to-back, respectively pointing in two opposite directions to achieve bidirectional electromagnetic wave radiation. With the development of wireless communication systems, the market's demand for two-way radiation is not limited to radiation in two opposite directions, but three fixed points on the ground or three points in the air for simultaneous communication. [0003] The use of two-way radiation antennas in satellite communications can greatly improve the gain and directionality of two-way radi...
