A two element MIMO/diversity antenna with high isolation for WLAN applications is proposed. Two microstrip antennas (MSAs), with a spacing < 0.1λ0 is designed and optimized on a finite rectangular ground plane on a FR4 substrate to resonate at a central frequency of 5.8 GHz. Isolation is improved by three means. Three pair of slits of different sizes are etched at different positions in the ground...
This article highlights the effect of superstrate height on gain of MSA fed Fabry Perot Cavity (FPC) antenna. The FPC antenna structure consists of a microstrip antenna, which feeds an array of square parasitic metal patches fabricated on a FR4 superstrate. These patches are good reflector of microwave frequency and therefore are used to enhance the reflection coefficient and the gain. Field amplitude...
