Microstrip-fed cavity-backed slot antennas | Zhongxiang Compared with basic microstrip patch antennas, wide-slot cavity-backed antenna, proposed by Hirokawa, Arai, and microstrip-fed slots have the advantages of wider bandwidth, less Goto [10], was fed by a metallic feed line of negligible radius interaction via surface waves, and better isolation from feed net- matched with the coaxial cable of 50 ⍀. Microstrip Fed Slot Antenna | Antenna Magus The Microstrip slot antenna is a variation of the conventional resonant slot. The microstrip feed makes it possible to fabricate an array of these antenna elements and their feed network on the same substrate. Slot antennas have bidirectional radiation patterns which can easily be directed with a metallic cavity …
The configuration of the proposed CSRR-fed SIW cavity-backed fractal patch antenna is illustrated in Figure 1. It consists of three metallization layers and a stack of two substrates with thicknesses of h 1 and h 2 and relative dielectric constants of ε r 1 and ε r 2 , respectively.
