Wide bandwidth, high-gain slot-loaded rectangular microstrip antennas

The effect of slot on patch and on ground plane of rectangular microstrip antenna for effective size reduction, wide bandwidth, and high gain has been presented. A 60.57% of virtual size reduction is achieved by taking ground plane same as that of patch on another similar substrate and by keeping 1‐...

Description
Summary:The effect of slot on patch and on ground plane of rectangular microstrip antenna for effective size reduction, wide bandwidth, and high gain has been presented. A 60.57% of virtual size reduction is achieved by taking ground plane same as that of patch on another similar substrate and by keeping 1‐mm air gap between them. Furthermore, 51% of bandwidth and 8.73 dB of gain are achieved by embedding group of slots on the patch, wide slot on the ground plane and by doubling the thickness of substrate. © 2010 Wiley Periodicals, Inc.
