Wide Bandwidth, High-Gain, and Low-Profile EBG Prototype for High Power Applications

In this letter, we present a wide-bandwidth, low-profile, and high-gain electromagnetic band-gap (EBG) resonator antenna that is used for high power and electronic warfare applications. It presents a bandwidth of 71% (from 1 to 2.1 GHz) and a maximum gain of 17 dB. The profile of this antenna is very low (22 mm, which is equivalent to λ/11 at 1.2 GHz). A prototype of this modeled antenna is manufactured, and the measured performances are similar to the simulated ones.
