Frequency-reconfigurable water antenna integrated with solar cell

Abstract

A frequency-reconfigurable antenna integrated with solar cell is presented in this paper. The solar cell is used as a conducting plane and antenna is constructed by cutting a slot on the solar cell. The solar cell slot antenna is fed by a microstrip line under the solar cell. Moreover, water is employed as a reconfigurable and transparency dielectric loading for the antenna. The center frequency of the antenna can be changed by tuning the height of water. The proposed design can achieve a slot antenna with continuous tuning frequency range from 450 MHz to 1000 MHz is achieved.
