A Frequency- and Pattern-Reconfigurable Rotatable Antenna Array
A frequency- and pattern-reconfigurable rotatable antenna array is proposed in this paper. The frequency-tunable mechanism is achieved by varying the capacitance value of the loaded varactor and the rotatable motion of the antenna structure, which contains three two-element arrays. Two independent bias voltages provide the pattern reconfigurability for each two-element array. It is achieved by introducing phase shift between the two array elements. The mechanism of quasi-Yagi antenna is used to enhance the gain. The proposed design has a frequency-tunable band from 2.66 GHz to 3.72 GHz, and a maximum continuously beam-scanning angles from −28° to +29° across broadside.
