Two Element Series Fed Origami Antenna

Origami inspired antennas have been investigated for their potential as lightweight and efficient multi-purpose reconfigurable antennas for a variety of radio frequency applications. Being able to change antenna frequency, bandwidth and gain simply by folding the antenna structure is certainly attractive, however, challenges must be overcome for real-world applications. Providing sufficient gain is a challenge for small antennas and this issue can be compounded by impedance matching problems resulting from folding the antenna feedlines. Providing sufficient structural strength along with a reliable means to physically fold the antenna can also be a challenge. In this paper a novel origami inspired two-element hexagonal antenna array is investigated for its potential to provide a simple and stable physical structure that demonstrates consistent gain and impedance matching for multiple configurations.
