摘要：This paper discusses analysis and optimization for rectangular and U slit or slot loaded micro strip antenna. For analysis, many parameters have been varied to optimize the resonant frequency 15 GHz, upper frequency 21GHz and lower frequency 9 GHz. The dielectric permittivity of the substrate is considered 4.8. In this paper we specially emphasize on the height of the substrate. By changing the height of the substrate from 1mm to 3.2mm. The patch will be fed by a micro strip transmission line, which usually has a 50#8486; impedance. The antenna is usually fed at the radiating edge along the width (W) as it gives good polarization, however the disadvantages are the spurious radiation and the need for impedance matching [1]. This is because the typical edge resistance of a micro strip antenna ranges from 150#8486; to 300#8486; [2]. The bandwidth is optimized from 754.13 to 4196.50 MHz for rectangular patch and 949.90 to 207099.33 MHz for parasitic patch.
