Multi-director micro-strip Yagi antenna

Abstract

The invention discloses a multi-director micro-strip Yagi antenna. The multi-director micro-strip Yagi antenna comprises a substrate, a rectangular micro-strip metallic grounding plate, a rectangular micro-strip radiation paster, a plurality of rectangular micro-strip directors and an impedance matching incoming feeder, wherein the rectangular micro-strip metallic grounding plate, the rectangular micro-strip radiation paster and the rectangular micro-strip directors are arranged on the front face of the substrate, and the impedance matching incoming feeder is arranged at the lower end of the back face of the substrate; the rectangular micro-strip metallic grounding plate is horizontally arranged at the lower end of the front face of the substrate; the rectangular micro-strip radiation paster and the rectangular micro-strip directors are sequentially arranged between the rectangular micro-strip metallic grounding plate and the upper end of the substrate from bottom to top; the rectangular micro-strip radiation paster comprises a left rectangular micro-strip radiation paster and a right rectangular micro-strip radiation paster, and the left rectangular micro-strip radiation paster and the right rectangular micro-strip radiation paster are separately connected with the rectangular micro-strip metallic grounding plate through micro-strip lines; the rectangular micro-strip directors are arranged sequentially from bottom to top. According to the multi-director micro-strip Yagi antenna, the size and weight are reduced, and meanwhile, the device has stable orientated radiating capacity and high gain through introducing the rectangular micro-strip directors.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a multi-director microstrip Yagi antenna. Background technique [0002] With the continuous development of electronic countermeasures and modern mobile communication technology, the equipment has higher and higher requirements for antennas with small size, light weight and high gain. Very popular, but the traditional Yagi antenna is bulky, which limits its application in mobile communications and other space-constrained environments. The microstrip antenna is a planar antenna, which is made of a thin dielectric sheet, set The geometric metal radiating elements on the top layer and the ground metal on the bottom layer of the thin dielectric sheet have developed rapidly in the field of antenna technology in recent decades due to their advantages of light weight, small size, simple fabrication and easy integration. [0003] Therefore, how to combine the design concept of the Yagi ...
