TLDR
In this paper, a new reconfigurable origami bifilar helical antenna is presented, which can change its operating frequencies by changing its height, and analytical equations for the design of such antennas are derived based on an equivalent model of a standard helical antennas.Abstract:
This communication presents a new reconfigurable origami bifilar helical antenna. This antenna can change its operating frequencies by changing its height. Also, analytical equations for the design of such antennas are derived based on an equivalent model of a standard helical antenna. An origami bifilar helical antenna is designed and its performance is verified using simulations and measurements.read more
