Description
technical field [0001] The invention relates to a linearly polarized wave arbitrary polarization angle deflector, which belongs to the field of electromagnetic technology. Background technique [0002] Under the condition of informatization, the threat of electromagnetic interference from the outside world to frequency-using equipment is increasing, and the propagation control of electromagnetic waves has become a hot spot in the field of electromagnetic research. [0003] In communication technology, using different polarizations has different propagation characteristics, combined with the polarization characteristics of the transceiver antenna, the best transmission and reception of electromagnetic waves can be achieved. Medium-wave broadcasting adopts vertical polarization propagation, and TV signals and FM broadcasting are space direct wave propagation, not ground wave propagation. Unlike the above-mentioned situation where horizontally polarized waves propagate on the e...
