Multilayer Effects on Cavity-Backed Slot Antennas

Radiation of High-Gain Cavity-Backed Slot Antennas Through a Two-Layer Superstrate

“…It was also reported that a dielectric overlay can enhance the gain of slot antennas [29,30]. The multilayer effect on cavity-backed slot antennas was studied in [31]. It was noted that the gain of a superstrate-covered cavity-backed slot antenna as described in [3 1] and [32] was less than 10 dBi.…”

A broadband cavity-backed slot antenna design with small cavity height and analysis on large ground plane

“…In [8], design of CBS antenna with inverted feed is proposed and the advantage of inverted feed in terms of higher gain and higher bandwidth are discussed. In [9], the effect of multiple superstrate layer on the slot antenna has been studied and it is concluded that the performance of CBS antenna is less affected as compared to that of cavity backed patch antenna. The radiation pattern of antenna for finite ground plane has been analyzed in [10][11].…”

Design of a High-Gain Cavity-Backed Slot Antenna With Mushroom Cells and Bent Ground Walls

“…Cavity-backed slot antennas are extensively used in satellite communications and airborne phased arrays [12][13][14][15][16][17][18][19][20][21], because of their unique features: (i) they can provide unidirectional radiation, (ii) mutual coupling between elements is relatively low, which is desirable in the design of phased arrays; and (iii) they can be readily mounted flush to the surface of a flying object. It was noted that the gain of a superstrate-covered cavity-backed slot antenna as described in [16][17][18][19][20][21] was between 9.8 and 16.7 dB.…”
