Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] The device provided by the invention is a device capable of improving a microstrip antenna, and the device is mainly composed of a microstrip antenna and a pair of metal conductive walls.

[0020] The present invention is based on the traditional microstrip antenna design. The traditional microstrip antenna is composed of a feeding part, a metal floor, a dielectric plate and a radiation metal patch. Add a metal conductive wall. The metal conductive wall is no more than 0.2λ from the edge of the microstrip antenna radiation metal patch, and λ is the wavelength of the antenna center frequency. The metal conductive wall has a rectangular structure, and one end of the metal conductive wall is connected to the metal floor of the microstrip antenna. To form an overall structure, the height of the metal conductive wall and the distance from the microst...

Abstract

The invention provides a device for improving a wide beam of a micro-strip antenna, and belongs to the technical field of aerospace engineering. Based on a conventional micro-strip antenna design, both sides of an electric-field surface of the micro-strip antenna are provided with metal conductive walls on the premise of not changing an antenna structure. After the antenna structure is changed simply, the radiation performance of an element pattern is changed; radiation wave beams of the antenna are broadened; a half-power beam width of the antenna can be increased; and the half-power beam width can be up to 150 degrees at the same time on an E side and an H side. After the conductive walls are added, a half-wave power angle of the antenna is increased, and the beam width performance of the antenna is improved remarkably.

Description

technical field [0001] The invention belongs to the technical field of aerospace engineering, in particular to a microstrip antenna device. Background technique [0002] In satellite communication applications, an essential requirement for ground mobile communication terminal antennas is a wide beam, because in this way, a wide range of elevation angle and azimuth signal reception can be achieved to meet communication requirements. On the other hand, the phased array radar system has been widely used because the beam pointing can be flexibly controlled. Due to the influence of mutual coupling between array elements and the limitation of the beam width of the element pattern itself, the gain of the antenna array drops greatly when the beam sweeps to a wider angle. For example, the gain of the phased array antenna of the microstrip antenna unit drops by 4 to 5 dB when the beam scans to ±50 degrees. Therefore, there is an urgent need for a wide-beam element antenna. At prese...
