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.
This paper presents a reconfigurable axial mode helical antenna which could be folded and unfolded using rigidly foldable origami structure to work at different resonant frequencies for kinds of wireless systems. Measured results show that the folded state could operate at both 1.82 GHz and 2.14 GHz. And the measured operating frequency for the unfolded state is 860 MHz. The frequency reconfigurability...
