Abstract

The invention belongs to the technical field of antennas and in particular to a dual-band vortex electromagnetic wave array antenna, and mainly solves a technical problem that a conventional array antenna cannot radiate vortex electromagnetic waves on dual bands. The dual-band vortex electromagnetic wave array antenna includes a dielectric substrate, an upper antenna array, and a lower antenna array. The upper antenna array and the lower antenna array have the same structure and are mounted on the upper surface of the dielectric substrate respectively. An intersection angle [alpha] between thecenter line of the upper antenna array and the center line of the lower antenna array is 42 degrees. The dual-band vortex electromagnetic wave array antenna is reasonable in design and compact in structure, solves the technical problem that the conventional array antenna cannot radiate vortex electromagnetic waves on dual bands, and is suitable for wireless communication.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a dual-band vortex electromagnetic wave array antenna. Background technique [0002] The angular momentum of electromagnetic waves includes spin angular momentum and orbital angular momentum. Electromagnetic waves carrying orbital angular momentum are different from ordinary plane waves. The center intensity of the beam is zero, and the phase wave front presents a spiral characteristic, also known as vortex electromagnetic waves. The vortex electromagnetic wave uses the mode number m to represent the rotation degree of its phase wave front. Theoretically, there are infinitely many modal numbers m of the vortex electromagnetic wave, and there is orthogonality between different modes. Using this vortex electromagnetic wave This feature can greatly improve the spectrum utilization and communication capacity of the communication system. [0003] Orbital angular momentu...
