Abstract (in Japanese) (See Japanese page) 
(in English) Recently, a leaky wave antenna using a composite right/left handed (CRLH) technique has been studied in microwave and millimeter-wave band. The leaky wave antenna using the CRLH transmission line (CRLH-TL) has broadband characteristics in operating band due to additional left-handed branch. And the frequency tunable antenna using the CRLH-TL can be achieved for variable beam direction from backfire to end-fire. And wide band and small antenna for UHF band is required because terrestrial digital broadcasting service has started.
In this paper, radiation characteristics of leaky wave antenna using CRLH-TL composed of ladder network has been investigated for UHF band. The transmission characteristics, bandwidth and attenuation constant of the CRLH-TL are discussed. And the effects of finite number of cells of the leaky wave antenna using CRLH-TL for UHF band are clarified to the radiation characteristics, gain and beam direction.
