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 ⍀.

The field distribution in the slot, therefore, is dependent on the excitation of higher cavity modes as well as the principal mode (TE10). The equivalent circuit of a cavity-backed slot antenna is shown in Figure 8-7b; the shunt conductance is the radiation conductance of the slot.

The equivalent circuit of a cavity-backed slot antenna is shown in Figure 8-7b; the shunt conductance is the radiation conductance of the slot. The conductance of the cavity-backed resonant half-wave slot is half the open slot, free to radiate on both sides. That is, the shunt resistance is at least 800 rather than 400 Ω.14–16

DESIGN OF A HIGH-GAIN CAVITY-BACKED SLOT ANTENNA WITH ...
Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear. Cavity backed slot antenna array - YouTube Enter a description for your creation here.
