Design and Fabrication of Aperture Coupled Microstrip Increased Bandwidth Antenna
Keywords:
Aperture coupled microstrip antenna, bandwidth enhancement, coupling, resonant frequency, slotAbstract
This paper presents aperture coupled microstrip antenna with three resonants. The antenna bandwidth has been enhanced due to clip in the patch edges and varies the current distribution well in order to create the third resonant. There is a compromise between radiation characteristics and the antenna bandwidth. These two factors have been optimized in designed and fabricated samples. E-plane and H-plane patterns indicate the appropriate propagation pattern of antenna is between 1.3 to 2.3 GHz frequency band, which clarifies achieved bandwidth more than 53% by using certain method in the novel one radiating element. Of course, there is bandwidth enhancement up to this limit by utilization of multiple radiating elements.
