Abstract
This paper presents a novel design of ultrawideband origami quasi-taper antenna that can be reconfigured to operate from 1.28 GHz to 4.12 GHz at 3 different states of height, and the operating bandwidths at the 3 states are respectively 1.28 GHz-1.64 GHz (25%), 1.64 GHz-3.56 GHz (74%) and 3.56 GHz-4.12 GHz (14.6%). Therefore, this antenna can be applied for kinds of wireless communications in L band and S band with unidirectional radiations. Simulated realized gain at the 3 states of antenna height in their operating frequency bands are respectively greater than 6 dB (H=271 mm), 8.5 dB (H=147 mm) and 5 dB (H=57 mm). Right-hand circular polarization happens at state 2 from 2.04 GHz to 3.56 GHz (fractional circular polarization bandwidth=54%), and the CP bandwidth is better than the standard monofilar and previously proposed origami conical spiral antenna, while polarizations at the other 2 states are either linear or elliptical in their operating frequency bands.
