Abstract

The invention relates to a special-shaped radiating element circular polarization planar antenna which comprises a radiating layer, a coupling layer and a feed network, wherein 16 radiators are arranged on the radiating layer and are arranged in four rows and four lines. The special-shaped radiating element circular polarization planar antenna is characterized in that each radiator is a special-shaped radiator, wherein a groove of a chamfered square column structure is formed in one side of the radiator in the radiation direction; a radiating slot is formed in the side, opposite to the coupling layer, of the radiator; the radiating slot is communicated with the groove of the chamfered square column structure; the feed network is a feed network for a linear polarization planar antenna. By improving the structures of the radiators of the radiating layer, the gain of the special-shaped radiating element circular polarization planar antenna is greatly improved, the efficiency is also improved greatly, and signal quality is substantially improved; the overall physical dimension of the planar antenna is not changed, therefore, the processing and manufacturing cost of the planar antenna is effectively lowered, and after-sale installation and usage are facilitated.

Description

technical field [0001] The invention relates to a circularly polarized panel antenna with a special-shaped radiation unit, belonging to the technical field of satellite communication. Background technique [0002] Satellite communication has the advantages of large coverage, large communication capacity, high transmission quality, convenient and rapid networking, and easy global seamless link. With the increase of satellite communication channel capacity and the congestion of C and Ku frequency band services, L, C, X, Ku and other frequency bands cannot meet the application requirements of high-speed, broadband, and small-caliber terminals. There is an increasing need for satellite communication systems that work in higher frequency bands, have larger bandwidths and higher spectral efficiency. Ka-band satellite communication has become an inevitable trend of future satellite communication due to its advantages of large available bandwidth, large communication capacity, narr...
