THE INFLUENCE OF NON-LINEAR CHARACTERISTICS OF THE RF SWITCHES UPON THE PATTERN OF THE RECONFIGURABLE ANTENNA

摘要

The results of simulation of the microstrip two-frequency reconfigurable antenna pattern are provided in the paper. The influence of MEMS-switches possessing non-linear volt-farad characteristics and the level of excitation exerted upon the antenna characteristic is considered. It is shown the necessity of analyzing the reconfigurable antenna parameters not only at the basic frequency but also at the frequencies of harmonics (subharmonics). On the basis of the results obtained in the paper it is noted that this class of the antennas can be used at creating the multi-functional devices - the multiplier antennas, the interference-generating antennas etc.
