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. Slot Antenna - an overview | ScienceDirect Topics The planar form of the slot antenna with CPW feeding is shown in Figure 11.18. Unlike the waveguide slot antenna that is excited from one side, the planar slot antenna demonstrates bidirectional radiation, which limits the application of this antenna. Alternatively, the slot may be either cavity- or reflector-backed to eliminate backside radiation at the cost of additional bulk and complexity.

A wideband cavity-backed slot antenna operated in the ultra-high frequency (UHF) band is introduced. The antenna has a compact structure and low profile with the size ratio of the ground plane to the slot only 1.6:1. The measured impedance bandwidth of VSWR⩽3 achieves 85.3%, covering a frequency range from 390 MHz to 970 MHz.
