| Summary: | The new construction of the broadband loop antenna with possibility of polarization control by excitement of the antenna on two isolated inputs is described. The designed antenna has a small size, low level of radiation with cross-polarization, directive gain 7…8 dB and the half power beamwidth about 70° in the E -plane and 86° in the H -plane. The bandwidth of the antenna, which provides maximum SWR SWRMAX = 1.3…2.0 is (24…54) %. The results of antenna geometric parameters optimization on the maximum of the frequency band for various values of the maximum SWR level in the working frequency range are presented. The obtained results can be used in designing of antennas for radiosystems with controlled polarization. |
