Abstract:
A compact wideband planar microstrip-fed quasi-Yagi antenna is presented. In order to achieve a high gain, the traditional rectangular director in one row is replaced by two rows of directors with an angle, and the overall size of the antenna is unchanged. By adjusting the angle between the two rows of directors, a better performance is achieved. The measurement results show that a broadband impedance about 85.5% (1.84-4.59 GHz) for S11 less than -10 dB and a gain about 4.5-9.3 dBi are obtained. Simulation and measurement results are provided and discussed. The agreements between the simulation and measurement results indicate that the antenna is suitable for wireless communication applications and phased arrays.
