Study on the wide band tunable disc antenna
Translated Abstract
In order to realize the wide band tunable antenna, under the circumstance of without any increase in volume, a dual port disc antenna is proposed. Through the two orthogonal placed ports fed at the same time, the resonant modes superposition is obtained, which greatly expanded the bandwidth of the disc antenna. When changing the phase difference of the two ports, the antenna’s impedance bandwidth is changed followed by the phase difference of the two ports, realizing the wide frequency range tunable. Hence, the dual port disc antenna achieving wide frequency tunable only need a phase shifter adding to one of the port, which can change the frequency by controlling the output of the phase shifter.
