results for trapezoidal slot give bandwidth of 287.2 MHZ (11.93% fractional bandwidth). Feed point on the patch that gives a good match of 50 ohm. Keywords: bandwidth, RMPA, design, enhancement, trapezoidal, slot. 1. INTRODUCTION Microstrip antennas are popular for their attractive features such as low profile, low weight, low CHAPTER 4 BANDWIDTH ENHANCEMENT OF THE ANTENNA - Shodhganga Time Domain approach have been used for computation of the results presented in the chapter. 4.1 Need for Bandwidth Enhancement Primary barriers to implement patch antennas in modern broadband communication system applications are their narrow bandwidth. The microstrip antennas are often realized with bandwidth of the order of 1% to 5%. Bandwidth Enhancement of Planar Slot Antenna Using ... Abstract: Traditional coplanar waveguide (CPW)-fed planar slot antennas are inherently narrow in bandwidth. Widening open-ends of the slot and adding parasitic elements are popular techniques for bandwidth enhancement. An alternative approach is to apply complementary sources. C-Shaped Slot Serves UWB Antenna - mwrf.com As a result, numerous UWB antennas with a notched function have been developed for UWB communication systems. 8-11 To achieve these antenna designs, different slot shapes have been proposed, such as adding an inverted-L shaped, V-shaped, or hybrid-shaped slot 12-15 to a planar monopole.

A Novel approach for Stacked Patch antenna for large
In this paper, a new approach is presented for omitting the cut-off frequency of the waveguide. This approach is easy to implement and low cost and can enhance the gain by using quasi-TEM mode propagation. In addition, it is suitable for miniaturization of slot antennas, filters, and passive and active circuits. 2. Bandwidth enhancement and size reduction of microstrip slot ... WET 38 Bandwidth Enhancement and Size Reduction of Microstrip Patch Antenna by Magnetoinductive Waveguide Loading patch antennas as superstrate and substrate to enhance resonators are used to design this MI waveguide [7]. the gain, bandwidth, directivity as well as to achieve The objective of this paper is to present a squared split ... A NOVEL FREQUENCY RECONFIGURABLE SLOT ANTENNA - IJAET A novel frequency reconfigurable slot antenna is designed for cognitive radio system. In cognitive radio system the two antennas are required one is a wideband antenna and another is frequency reconfigurable antenna.
