Study on a leaky wave antenna for high gain

Ju Jeong Ho; Eom Sung Yong; Kim Joung Myoun; Song Myung Sun; Choi Jae Ick

A leaky wave antenna(LWA) is studied by using dispersion diagram. The advantages are a simple design, a low profile, and high boresight directivity over the frequency bands. Moreover, the radiation properties of the leaky wave are investigated by means of the theoretical analysis by using dispersion properties of a unit cell for the LWA. The measured and predicted results verify the performance of the antenna.
