Abstract :
In this paper, we describe the design and the experimental implementation of a new aperture-coupled microstrip antenna for broadband applications in wireless systems. Using an aperture-coupled feed method, a rectangular microstrip patch employing a multilayer substrate structure was designed and built. The main motivation of this work was to develop large bandwidth antennas for the PCS band 1850-1990 MHz. The new prototype is characterized by a 10% bandwidth around the center frequency of 1.90 GHz and a low front to back ratio. To examine the performances, numerical results, measurements of S-parameters and radiation patterns are presented
