Cavity Antennas

Rectangular and circular cavity

Antennas performance can be improved using two kinds of backing structure like cavity antennas. Cavity backing helps to reduce back radiation.

Double-Slot Cavity Patch on TMM10 Substrate

Create a custom slot cavity patch using custom antenna geometry and thick dielectric substrate. A double slot cavity patch consists of a double slot patch, backed by a cavity and probe-fed. The cavity is filled with TMM10 substrate. The cavity backing helps to reduce back radiation. You can use this antenna for microwave imaging by placing the antenna close to the human body.
