Why most of the Research papers have chosen dielectric constant near about 10 for DRA based RF Energy Harvesting ?

04 May 2025 1 2K Report

Dielectric constant of Dielectric Resonator Antenna design for RF Energy Harvesting in IoT application. Need some reference also.

Malcolm White

Probably because they are using alumina ceramic for the resonators, which is fairly low loss and has a dielectric constant close to 10, and is cheap.
