【 摘 要 】
In this paper, a modified microstrip slot aperture feed is introduced which generates TEÏ13 modes in a cubic dielectric resonator antenna resulting in a high gain (simulated = 10.5 dB and measured = 9 dB). The proposed feed can be realized by replacing the rectangular stub of microstrip slot aperture feed with a circular metallic stub of radius 3 mm. The proposed feed excites the dielectric resonator antenna around a resonant frequency of 5.78 GHz covering 5.725â5.850 GHz WIFI band. The antenna exhibits an impedance bandwidth of 130.2 MHz, and 135 MHz in simulations and measurements respectively, and a stable gain throughout the 5.78 GHz WIFI band with a maximum of 9 dB in measurements.
