基于多模态OAM涡旋电磁波的L波段宽频阵列天线设计
The Design of L Band Broadband Array Antenna Based on MuIti-modaI OAM Vortex EIectromagnetic Wave
摘要
Abstract
The shortage of spectrum resources becomes a bottleneck in the development of wireless communication. This paper applies the technology of orbital angular momentum (OAM)to the design of array antenna and uses the micros-trip patch antenna with feeding type of L probe as an element.The elements are arranged along the circumference equidis-tantly to present an 8-element broadband microstrip array antenna generating multi-modal OAM vortex electromagnetic waves and the adjacent elements are fed with the different phases.The operating frequency band of the antenna ranges from 1.35GHz to 1.86GHz,and meanwhile,the relative bandwidth can reach 31.8%.Experiment results show that the array an-tenna can generate electromagnetic waves with characteristic of multi-modal orbital angular momentum.When it is placed in the transmitting terminal of wireless communication system,the multiple signals can be transmitted on the same frequency simultaneously,which improves the transmission rate and capacity of the communication system.关键词
