A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters. Single & Double Diamond Circular Microstrip Patch Antenna The results of both single and double diamond antenna are shown here: that is return loss, VSWR, Smith Chart and Radiation Pattern etc. In the both circular antenna design we can see that if we reduce size of antenna the all output parameters are remain same. In this we can design compact size antenna. Fig. 3 :- Return loss of single diamond circular microstrip patch antenna Fig.3 shows that ... Dual slot microstrip antenna device - Ball Brothers ... A dual slot antenna assembly is disclosed herein and generally includes a pair of concentrically positioned and radially spaced cylindrical conductors defining a pair of circumferential slots which are longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna device.
The RX antenna consists of an array of 8 × 8 single slot antenna elements according to Fig. 10 below. Figure 11 shows the complete manufactured TX and RX antenna with a metal frame foot print for the metal back cavity assembly. The metal frame is grounded using microvias to the ground plane. V. CAVITY-BACKED ANTENNA
