Publication number: 20110279342Abstract: A wideband antenna including a ground element, and an antenna body provided on the ground element with a predetermined distance. The antenna body includes a feed element and a dielectric substrate, wherein an annular passive element is provided on the top surface of the dielectric substrate with a predetermined gap from the feed element. A plural short-circuit pins are equally spaced on the outer periphery of the passive element, whereby the passive element and the ground element 17 are connected by the short-circuit pins. A slit is formed on the passive element in the vicinity of the short-circuit pins. Since the slit is formed on the passive element, a resonance circuit having a resonance frequency dependant on the shape of the slit is formed on the passive element in the vicinity of the slit, whereby the radiation of the frequency component from the feed element is prevented.Type: ApplicationFiled: October 29, 2009Publication date: November 17, 2011Applicant: NIPPON ANTENA KABUSHIKI KAISHAInventors: Fumio Takahashi, Hiroshi Shimizu, Hisamatsu Nakano, Shunichi Yamazaki
