Antenna with one-way circular polarization |
摘要 |
An antenna having one-way circular polarization is of the type comprising a radiating element associated with a frequency filter. It comprises a polarization-selective device disposed at the transition between the frequency filter and polarizer means adapted to cause the wave to be circularly polarized. This multimode selective device is adapted 1) to enable the initial go mode to propagate, 2) in transmission, to pass one of the return modes induced by the polarizer means, and 3) to reflect the other return mode. At the polarizer, the wave made up of the initial mode and of the reflected return modes reinforces the circular polarization of the initial mode. Such an antenna can be made as a single piece of size and weight that are smaller than those of known antennas having one-way circular polarization.
