Abstract

The invention relates to a wireless communication antenna device, which comprises a loudspeaker antenna and a wave guide pipe, wherein the loudspeaker antenna is used for emitting or receiving a polarized radio wave signal, the polarized radio wave signal is provided with a first component electric field and a second component electric field which are orthogonal to each other, the wave guide pipe is connected with the loudspeaker antenna and is used for transmitting the polarized radio wave signal, and in a first opening of the wave guide pipe, the edge length corresponding to the first component electric field, is different from the edge length corresponding to the second component electric field, so a phase difference exists between the first component electric field and the second component electric field when the polarized radio wave signal is transmitted in the wave guide pipe. The wireless communication antenna device has the advantages that the phase characteristics of the polarized radio wave transmission are improved, and in addition, the linear and spinor wave polarized conversion performance can be optimized.

Description

technical field [0001] The present invention relates to a communication device, and in particular to a wireless communication antenna device. Background technique [0002] With the rapid development of electronic communication technology, the use of wireless communication as a signal transmission medium has become the mainstream, and there are many types of antennas used in wireless communication systems, such as: Dipole Antenna (Dipole Antenna), Monopole Antenna (Monopole Antenna) , Microstrip Antenna (Microstrip Antenna), Horn Antenna (Horn Antenna) and Dish Antenna (Dish Antenna) and so on. Among them, the dish antenna is widely used in satellite communication systems and terrestrial microwave transmission systems because of its advantages such as high directivity and high gain. [0003] In the dish antenna system, due to consideration of the radiation efficiency of the antenna, the horn antenna (for example: elliptical horn antenna) can be used as a better form of the f...
