A beam-switchable coupled feeding network in X-band

An antenna feeding network is proposed for a driving system.It consists of branch line couplers, Wilkinson power dividers, and asymmetric delay lines. Using an orthogonal beam property and an antenna sharing technique, its radiation patterns are measured at 10 GHz. The measured beam coverage angle w...

Description
Summary:An antenna feeding network is proposed for a driving system.It consists of branch line couplers, Wilkinson power dividers, and asymmetric delay lines. Using an orthogonal beam property and an antenna sharing technique, its radiation patterns are measured at 10 GHz. The measured beam coverage angle was 70° (−35° to +35°) in the five input ports by using eight radiating elements. © 2010 Wiley Periodicals, Inc.
