In this paper, the design and analysis of circular microstrip patch antenna with plus shape for the WLAN and WiMax application is presented. The operating frequency of antenna 4.7GHz having circular shape. The antenna design consists of a single layer of substrate with thickness 1.6mm having dielectric constant of 4.4. The simulation results of proposed slotted circular microstrip patch antenna have been obtained by IE3D Zealand software. The effects of different parameters like return loss, radiation pattern are studied.
