Triangular Patch Yagi Antenna with Reconfigurable Pattern Characteristics
Keywords:
Microstrip antennas, pattern reconfigurable antennas, Yagi-Uda arraysAbstract
A pattern reconfigurable Yagi patch antenna is proposed. The antenna is composed of three triangular microstrip patches, i.e., one driven patch and two parasitic patches. By controlling switches, which are installed on the parasitic patches, the radiation pattern of the antenna can point to three different directions, covering an elevation range from -61° to +63° in the E-plane. The simulated and measured results are presented and they agree with each other in reasonable precision.
