Abstract: A rectangular microstrip patch antenna with defected ground structure with E-shaped and square shaped slot on the patch is proposed here. The proposed antenna design consists of H-shaped defect on the ground plane. The complete antenna system is constructed on 45.4mm X 45.4mm X 1.6mm, FR-4 substrate with dielectric constant of 4.4 and substrate height of 1.6mm. The antenna mainly works in 4-6 GHz band. The various characteristics parameters of the antenna like return loss, voltage standing wave ratio, impedance, gain, bandwidth and radiation pattern are studied. The antenna is simulated using high frequency structured simulator software , simulated < -10dB, in the entire operating range of 4-6 GHz.The proposed antenna design is mainly focused for the wireless applications and is suitable for IEEE 802.11 WLAN standards in the bands 5.2/5.8 GHz and WiMAX standards in the bands at 5.5 GHz. In this design microstrip line feeding is used.
