This paper is 4-element modified with reflector as an antenna for digital terrestrial broadcasting. The element deformation batwing antenna is proposed. Input impedance got 50 Ω and wide-band characteristics in the simple power supply construction. In this paper, parallel combination batwing antenna of the 4-plane synthesis directionality was examined. The batwing element is arranged and is coupled in parallel, and the feed interval is half-wave length. Simple power supply construction and high-gain and wide-band characteristics were obtained by choosing the wavelength. This antenna is sufficiently usable also as the transmitting antenna for digital terrestrial broadcasting and a transmitting antenna of other repeater stations is thought.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
