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.
This paper presents an origami Quadrifilar Helix Antenna (QHA) which could work at different operating frequencies in Ultra High Frequency (UHF) band with different heights for optimum realized gain. This antenna is designed to be applied to space wireless communication with little limitations of storage or transportation due to a compact size. Principle of this design was first validated by the ideal...
