摘要：
A liquid crystal frequency tunable antenna with larger tuning range is presented. It is a traditional patch antenna, which is divided into four parts by three slots. Benefiting from the slots, this antenna can operate in TM10 mode and antiphase TM20 mode within the same frequency band. Through choosing the tunable material liquid crystal as the dielectric of the antenna, the resonant frequency of the two modes can be tuned at the same time. Consequently, the frequency tuning range of this antenna is doubled as compared with the traditional liquid crystal microstrip patch antenna. The simulation results show that the resonant frequency tuning range of the proposed antenna is from 21.7 GHz to 23.9 GHz (9.6%), which is two times bigger than that of traditional liquid crystal microstrip patch antenna (4.8%).
