Abstract

The invention discloses a microstrip antenna, an array consisting of the microstrip antenna, an array set and an array set group. The microstrip antenna comprises a grounding dielectric slab, and a radiation dielectric slab vertically arranged on the grounding dielectric slab and provided with radiation elements; a metallic film and a microstrip line feed circuit connected with the radiation elements are arranged on the lower surface and the upper surface of the grounding dielectric slab respectively; and the radiation elements are lanceolate, fan-shaped, spear-shaped, heart-shaped, oval or spoon-shaped. The microstrip array is a linear array formed by the radiation elements arranged on the radiation dielectric slab by row. The microstrip array set is in a leaf mosaic structure formed by the 2-8 microstrip arrays in a manner that the radiation dielectric slabs are in parallel, the grounding dielectric slabs are in the same plane, and the radiation elements are distributed in a staggered manner. With the adoption of the microstrip antenna, the array, the array set and the array set group, the working band of a receiving antenna is widened; the radiation elements have omidirection in the plane; and the utilization ratio of microwave energy is increased.

Description

technical field [0001] The invention belongs to the technical field of microwave energy transmission, in particular to a receiving antenna for microwave energy transmission, in particular to a microstrip antenna and an array, an array group, and an array group composed of the microstrip antenna. Background technique [0002] Microwave Power Transmission (MPT: Microwave Power Transmission) is to transmit energy directly from the transmitting end to the receiving end through free space. Generally, microwave energy transmission is divided into three steps: 1) Direct current (DC) power is converted into radio frequency energy, and transmitted through the transmitting antenna The radio frequency energy is emitted; 2) The radio frequency energy is transmitted at a certain distance in space; 3) The energy is collected at the receiving end and converted into direct current (DC) power. Since the microwave transmission loss is only atmospheric loss, rain attenuation, and shelter l...
