## Abstract Two types of cavity‐backed slot (CBS) antennas fed by a microstrip line and operating at 5.8 GHz are described in this letter. One is a broadband linearly polarized CBS antenna, which can provide 34% bandwidth for a 10‐dB return loss. The other is a circularly polarized dual T‐shape CBS

✦ Synopsis
The mutual coupling of hemispherical ca¨ity-backed slot ( ) antennas is in¨estigated theoretically. The method of moments MoM is used to find the magnetic currents in the slots rigorously. The currents are then used to find the mutual admittance using the reaction theorem. The results are compared with those of the open slots.

The effect of dielectric loading in EC-SCPW on forwardcoupler characteristics has been studied. The dielectric loading increases the coupling coefficient and the frequency bandwidth, thus finding application in the propagation of narrow pulses. The size of the device can also be reduced considerably
## Abstract Slot antennas with a backing cavity for unidirectional radiation are investigated with the aim of achieving a thin structure capable of reasonably broadband operation. By tuning together the slot length and the cavity cross‐section, a very low‐profile cavity‐backed slot (CBS) is demonst
## Abstract A microstrip line coupled dielectric resonator antenna with an inclined and offset slot in the common ground plane has been analyzed. Excitation of the TE~111~ mode in this configuration is studied. It is also seen that the slot geometry and offset can be optimized to excite the higher
## Abstract This article describes a cavity‐backed slot antenna fed by a coplanar waveguide (CPW). The designed antenna operates at 30 GHz and uses an inverted configuration with the CPW feed line on the top of the substrate and the slot facing toward the metallic cavity. Both simulated and measure
