Abstract

The invention discloses a micro-strip quasi-Yagi antenna with a directional diagram being reconfigurable in a pitching plane. The antenna comprises an orthogonal laminated bistable composite material dielectric substrate, a micro-strip quasi-Yagi antenna layer laid at an upper layer of the bistable composite material dielectric substrate and a jump driver laid at a lower layer of the bistable composite material dielectric substrate, wherein the bistable composite material dielectric substrate adopts a [90n / 0n] lamination, the [90n] is adhered to the micro-strip quasi-Yagi antenna layer, and the [0n] layer is adhered to the jump driver. Reconfiguration of the directional diagram of the micro-strip quasi-Yagi antenna in the pitching plane is realized by using two types of stable configuration of the bistable composite material dielectric substrate. The micro-strip quasi-Yagi antenna is simple in structure and easy to be conformal with a carrier and can expand the scanning dimension of a Yagi antenna by combining a traditional Yagi antenna with the directional diagram being configurable in a horizontal plane.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to an antenna with a reconfigurable pattern, in particular to a microstrip quasi-Yagi antenna with a reconfigurable pattern in a pitch plane. Background technique [0002] With the control and scanning requirements of antenna beams in mobile communications, satellite communications, radars, and aircrafts, antennas with reconfigurable patterns have received more and more attention and development.
