This paper proposes a configuration of a new wide band microstrip patch antenna in wireless communications devices such as base stations. A New Novel wide band Π shaped microstrip patch antenna is presented with a wide impedance bandwidth of 67.8% centered at 5.5 GHz is achieved. The antenna structure is designed and simulated. Simulated results for the antenna parameters such as return loss, impedance bandwidth and the surface current distributions are discussed. The radiation patterns are obtained at 4.5 GHz, 5.5 GHz and 7.5 GHz. Due to three resonant slots on the patch it gives more bandwidth. This proposed Antenna is simple in structure with coaxial feed can well meet the wireless communication. The substrates are microwave substrate and foam material and the patch is placed on a thin dielectric layer, which is placed over the foam substrate. The simulated front to back (F/B) ratio is better than 20 dB throughout the frequency band)
