Analysis of Ε-patch antenna performance over various dielectric materials at 2.4 GHz

Antenna detuning can be used for a variety of sensing applications. In this paper, the performance of an E-patch and a conventional patch antenna was evaluated in the presence of dielectric materials. The gain penalty and the reflection coefficient of both the antennas were simulated and measured using a vector network analyzer. The performance of the E-patch antenna was evaluated to be much better than a normal patch antenna over each dielectric material. This analysis is useful for environmental monitoring, rescue, and surveillance applications.
