Bandwidth Enhancement of a Dual Band Planar Monopole Antenna Using Meandered Microstrip Feeding
A meandered-microstrip fed circular shaped monopole antenna loaded with vertical slots on a high dielectric material substrate (ε r = 15) is proposed in this paper. The performance criteria of the proposed antenna have been experimentally verified by fabricating a printed prototype. The experimental results show that the proposed antenna has achieved wider bandwidth with satisfactory gain by in...
متن کاملBandwidth Improvement of Microstrip Crossed Monopole Antenna
A compact size low profile microstrip-fed crossed monopole antenna for ultra wideband communication is presented. The impedance bandwidth of a microstrip crossed monopole antenna has increased with a suitable dimension of ground plane and rectangular patch. The aim of this paper is to improved bandwidth and return loss of a Crossed Monopole Microstrip patch antenna and study the effect of anten...
متن کاملBand-Rejected UWB Monopole Antenna with Bandwidth Enhancement
─ In this study, we present an UltraWideband (UWB) monopole antenna with bandnotched function. The proposed antenna is fed by a microstrip line. By using two modified forkshaped slots in the ground plane, bandwidth is increased that provides a wide usable fractional bandwidth of more than 135% (2.82-15.63). In order to achieve band-rejected performance, a cross-ring slot was inserted at the squ...
متن کاملEnhancement of Bandwidth in Microstrip Patch Antenna using EBG
This paper presents the bandwidth and gain enhancement of microstrip patch antenna using EBG for X band (10 Ghz) application. The surface waves must be suppressed to increase the bandwidth and gain by using EBG. By using EBG the stop band characteristics is created over certain frequency and that has been adapted to suppress the surface wave and to enhance the gain and bandwidth of the antenna ...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
