Frequency reconfigurable origami quadrifilar helical antenna with reconfigurable reflector

摘要

This paper presents a novel origami quadrifilar helical antenna (QHA) that can reconfigure its operating frequency between 2.07 GHz, 3 GHz and 4.45 GHz. An origami reflector was designed to enhance the gain of the QHA for all the operating frequencies. Typical simulated realized gains of this origami QHA with reconfigurable reflector are 15.13 dB at 2 GHz, 12.82 dB at 3 GHz and 15.13 dB at 4.45 GHz.
