Wideband Microstrip Antenna Design - arXiv aperture-coupled microstrip antenna (ACMSA) has been seen to achieve remarkably high bandwidths of nearly 70% with gain up to 8-9 dB [2]. The design of an ACMSA will be demonstrated as detailed in [3]. The following performance characteristics have been achieved: Center frequency f c = 575 MHz Antenna bandwidth BW = 250 MHz 2818 IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 53 ... A New Aperture Coupled Microstrip Slot Antenna Qinjiang Rao, Tayeb A. Denidni, Senior Member, IEEE, and Ronald H. Johnston, Senior Member, IEEE Abstract—A new aperture coupled design is proposed for mi-crostrip slot antennas to improvetheir radiation performance. The proposed design is based on a new aperture coupling technique in An Introduction Of Aperture Coupled Microstrip Slot Antenna Microstrip Slot designed in HFSS 29 Figure 4.5: Aperture coupled Wide-Band Micro Strip Antenna Design - ECE@IISc An aperture-coupled microstrip stacked patch antenna is studied with the goal .. 1. A microstrip line feeding network is used for impedance matching. Wu, L. US4847625A - Wideband, aperture-coupled microstrip antenna ...
The performance of the antenna has been confirmed by both measurement and simulation. The antenna gain is enhanced and backlobe radiation is reduced by placing a12. Adrian, A. and D. H. Schaubert, "Dual aperture-coupled microstrip antenna for dual or circular polarization," Electron.
Microstrip antenna consists of a conducting patch on upper side of dielectric substrate and a ground plane on the lower side of dielectric substrate.less coupling for a given aperture size, but wider bandwidth. · The back radiation level and the coupling level are determined by slot length. Back Radiation Suppression in Modified Aperture Coupled … A microstrip slot antenna for C Band has been proposed with compact structure and suppressed back radiation. In this paper, the feeding technique used is aperture coupling with a modification that patches and the feed line are positioned below the substrate and the slot is etched above the substrate.
