Guide antenna and design method thereof

The invention discloses a guide antenna and a design method thereof, and belongs to the technical field of antennas and microwaves. The antenna is composed of a main oscillator, directors and a reflecting plate, the main oscillator and the directors are each of a fan-shaped structure, the arc length of each fan-shaped structure is about one wavelength corresponding to the center frequency, and the main oscillator and the directors (the number of the directors can be multiple) can be located on the same plane of a dielectric substrate or can be located on different planes of the dielectric substrate. The working modes of the directors and the main oscillator can be tuned by using a mode disturbance device. The antenna has the characteristics of high gain, wide bandwidth and simple structure, and has a wide application prospect in future mobile communication and wireless communication. 本发明公开了一种引向天线及其设计方法，属于天线与微波技术领域。该天线由主振子、引向器和反射板构成，主振子、引向器均为扇形结构，其圆弧长度约为中心频率对应的一个波长，主振子与引向器(引向器的个数可以为多个)可以位于介质基板同一平面也可以位于介质基板不同平面
