This antenna consists of a rectangular slot, a beveled rectangular patch, two S-shaped slits cut in the ground plane and an elliptical ring slot (ERS) etched in the patch. The corners of a simple rectangular patch are beveled to improve the impedance bandwidth, especially at the middle frequencies of the band. Implementation of rectangular slit-inserted ultra-wideband To improve the bandwidth, rectangular slits were inserted in the tapered slot antenna, and the antenna area was reduced. The fabricated rectangular slit-inserted tapered slot antenna exhibited a bandwidth of 8.45 GHz and improved its bandwidth by approximately 4.72 GHz. Furthermore, the antenna showed a 15.5 % reduction in area. DESIGN AND ENHANCEMENT BANDWIDTH RECTANGULAR … In this paper the rectangular patch Antenna with (50) ohm coaxial feed has been designed. The impedance bandwidth of the designed antenna is 177.2 MHZ (7.31% fractional bandwidth). Whereas the impedance bandwidth of the antenna with single trapezoidal slot is 287.2 MHZ (11.93 % fractional bandwidth). That means, the bandwidth Compact Open-Slot Antenna With Bandwidth Enhancement Aug 18, 2011 · Abstract: A compact open-slot antenna for bandwidth enhancement is presented. Multiple resonances are generated by using an asymmetrical rectangular patch with the U-shaped open-slot structure. Two bevels are cut on the patch to improve the impedance matching.
