Description: Cavity backing of the conventional rectangular microstrip antenna is being proposed. The proposed antennas have been simulated. Improved values of Gain has been obtained from the proposed antenna. Results obtained for the cavity backed and without cavity-backed antenna has been compared. It has been found that by cavity backing the conventional antenna bandwidth increases many times.
CRA is an evolution of the antenna proposed by Roederer in 1990 [2]. Antenna is a rhomb shape microstrip over a ground plane as shown in Figure 1. Circular right or lef polarization depends on feed and load position. Radioengineering - April 2018, Volume 27, Number 1 [DOI: 10… The monopole antenna is modified using microstrip transition in the feedline and block with a triangular-shape slot on each side of the circular patch to produce wider impedance bandwidth with better return loss. US5519408A - Tapered notch antenna using coplanar waveguide… A radiating tapered notch antenna (sometimes known as a Vivaldi antenna) is fed by a section of slotline, which in, turn is fed by a coplanar waveguide. The transition from the unbalanced coplanar waveguide to the balanced slotline is …

This article presents a study of microstrip-fed cavity-backed slot (CBS) antennas using a new inverted configuration. The inverted structure places the metallic cavity in the slot side of the ... Enhanced-Gain Planar Substrate-Integrated Waveguide Cavity ... High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems. A number of enhancement techniques for antenna gain have been studied –.To realize enhanced-gain performance, a cavity-backed slot antenna (CBSA) is employed in this study because of its unidirectional characteristic. A cavity-backed coplanar waveguide slot antenna array A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. An Introduction of Aperture Coupled Microstrip Slot Antenna
