cavity-backed slot antenna (CBSA) - University of Nairobi In this paper, a rectangular Cavity Backed Slot Antenna (CBSA) Model excited by a probe is investigated. The analysis is carried out using the Alternating Direction Implicit - Finite Difference Time Domain (ADIFDTD) Method which is applied to investigate its characteristics in terms of … 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. Design Of A Wideband Dual-polarized Cavity Backed Slot …

Microstrip-fed cavity-backed slot antennas | Zhongxiang ... Detailed study of cavity-backed slot This article presents two types of cavity-backed slot antennas (CBS) antennas can be traced back three or four decades [5– 8]. A fed by a microstrip line and operating at 5.8 GHz: One is a linearly variational expression of the admittance of a rectangular CBS was obtained by Galejs [5], where the slot was excited by a current source across its center.
