Advanced Beam Reconfiguration in Horn Antennas Through Origami-Based Design

This paper introduces a novel horn antenna design that utilizes an origami-inspired, fan-fold aperture to enable advanced beam reconfiguration capabilities. The proposed antenna integrates a conventional H-plane sectoral horn with a shape-transforming origami structure, allowing for dynamic adjustments in beam shape, gain, and direction without the need for additional circuitry. Experimental results demonstrate that both double-sided and single-sided flaring configurations provide effective control over the radiation characteristics, with measured gains up to 8.8 dBi and beam steering up to 11°. This design offers potential applications in communication and radar systems, enhancing performance while maintaining simplicity and low fabrication costs.
