  Abstract

In this paper, U-Shaped slot Bow-Tie antenna for 5.15GHz~5.35GHz is designed, fabricated, and measured. The prototype consist of U-Shaped slot. To obtain suitable bandwidth, the form layer is inserted between ground plane and substrate. Important parameters in the design are U-slot length, width. position, air-gap height, and feed point position. From these parameters optimized, a U-shaped slot Bow-Tie antenna is fabricated and measured. The measured results of the antenna are obtained as follows results. The resonant frequency of the Fabrication U-shaped slot Row-Tie antenna is 5.28GHz, bandwidth for approximately 7.76%(VSWR<1.2) and the gain is 4~7dBi. The experimental far-field patterns are stable across the pass band. The 3dB bandwidth in Elevation and Azimuth are 73.6˚ and 65.08˚, respectively.
