Abstract
Conference Title: 2016 9th International Conference on Electrical and Computer Engineering (ICECE) Conference Start Date: 2016, Dec. 20 Conference End Date: 2016, Dec. 22 Conference Location: Dhaka, Bangladesh In this article a microstrip antenna is reported for wideband wireless communication application. The main radiator of this design is printed in the front side of a piece of FR4 dielectric substrate while a finite ground plane is etched on the rear side. To achieve wide operating band, the ground plane is reduced to partial one and defected by inserting slots on its upper edge. It is found that this modification established a proper coupling between ground structure and the radiator, and the investigated antenna attained a measured fractional bandwidth of 130%. Furthermore, the proposed antenna demonstrates omnidirectional radiation characteristics with good gain and efficiency.
