Low Profile Absorber Backed Extremely Wideband Antennas

In this paper design and electromagnetic performance of a low profile and extremely wideband antenna which works from 10 to 40 GHz is presented. The differentially fed antenna benefits from suppressed back lobe radiation by exploiting the use of a resistively loaded low profile absorber. The proposed antenna uses both the reflection and absorption phenomenon in near field and exhibits two octaves of bandwidth.
