چکیده
-Wide band truncated rectangular microstrip antenna with H slot loaded and defected ground plane structure is presented in this paper to increase the bandwidth. It is found that the impedance bandwidth of a microstrip antenna could be enhanced considerably when a defected ground structure is used .The band width of a truncated rectangular microstrip antenna with H slot is 21.2% whereas after adding the slot in the ground plane of a rectangular microstrip antenna with H slot the bandwidth is increase up to 29.0% ranging from 1.76 to 2.34 GHz. The radiation pattern has acceptable response at both E&H plane. The antenna is design at FR4 glass epoxy substrate with dielectric constant 4.4 fed by a coaxial feeding technique. Detail of the proposed antenna and the simulated results are presented. Keuwords bandwidth, broadband, microstrip antenna (msa), return loss, truncated rectangular microstrip antenna (trmsa).
