摘要

In this paper a Square patch microstrip antenna is designed with band notched characteristic of size 30 mm × 35 mm. The proposed antenna has wide frequency spectrum from 1.12 GHz to 9.75 GHz with VSWR less than 2, WLAN (wireless local area network) rejection for the frequency band 5.15 GHz-5.83 GHz is made possible by placing three parasitic patches on the bottom of the substrate. In this design no modification in radiating patch is required. Ansoft HFSS simulation software is used to obtain results of radiation parameters such as return loss, VSWR, radiation pattern and have satisfactory values within range.
