Abstract
In this paper, L-shaped slot antenna for 5.15㎓-5.35㎓ is designed, fabricated. and measured. The prototype consist of four L-shaped slot. To obtain suitable bandwidth, the form layer is inserted between ground plane and substrate. Important parameters in the design are four L-slot length. width, position, air-gap height. and feed Point position. From these parameters optimized, a four L-shaped slot antenna is fabricated and measured. The measured results of the antenna are obtained as follows results. The resonant frequency of the fabrication four L-shaped slot antenna is 5.25㎓, bandwidth for approximately 5%(VSWR<1.5) and the gain is 8-9㏈i. The experimental far-field patterns are stable across the pass band. The 3dB bandwidth in H-Plane and I-Plane are 69$^{\circ}$and 62$^{\circ}$, respectively.
