A Planar Monopole Antenna for Dual Band Application

This paper describes the design of a small dual band planar antenna to operate in the ISM (2.4-2.48 GHz) and WLAN (5-6 GHz) band. Dual band operation is achieved by choosing proper microstrip radiator shape and reduced ground plane which becomes a monopole antenna. Simulation of the antenna is carried out using CST Microwave Studio. The simulated results in terms of return loss and radiation patterns are studied. The designed antenna can be suitable for the ISM band (2.4-2.48 GHz) and WLAN (5-6 GHz) band.
