Abstract

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.

Description

technical field [0001] The invention relates to a design method of a directional antenna, which belongs to the technical field of mobile communication and microwave. Background technique [0002] At present, with the rapid development of wireless communication technology, the continuous improvement of mobile communication networks and the continuous construction of outdoor base stations, outdoor communication has been able to better meet people's needs, but indoor communication quality and indoor signal coverage are not perfect. Satisfactory. There are still a large number of mobile communication blind spots in closed areas such as underground parking garages, tunnels, mines, and elevators. [0003] In order to solve the problem of basically no signal or poor coverage in mobile communication in a closed environment, directional antennas with excellent performance have become the first choice for communication antennas in closed environments. Yagi antennas or logarithmic pe...
