Design and Evaluation of a Closely Spaced Yagi Antenna Over Ground

Abstract

In this paper, we present the design of a compact Yagi antenna with very close spacing between the elements. The major problem with a Yagi with closely spaced elements is that the radiation resistance is very small, leading to poor efficiency and poor matching. We apply the folding concept to step up the radiation resistance of the antenna to 50 Omega at… (More)
