This paper presents the increase in bandwidth of a microstrip antenna using a simple slotted structure in microstrip antenna. The main aim of proposed work is to obtain a large bandwidth antenna with reduced size. A new double Ψ -shaped microstrip antenna is presented, which increased the bandwidth of the E-shaped microstrip antenna by cutting an additional pair of two slots on the other radiating edge of the E-shaped patch. The double Ψ -shaped patch yielded 135 MHz bandwidth at a centre frequency of 2.4 GHz with 4.0db gain. The proposed antenna is designed and simulated on the HFSS software.
