Abstract

The invention discloses a highly directional antenna utilizing a radome with the structure of ring-shaped metal pair units; the antenna comprises a microstrip antenna array, a feed source connected with the microstrip antenna array and the radome of sandwich type consisting of the structure of ring-shaped metal pair units. The structure of ring-shaped metal pair units manufactured on an FR4 printed circuit board is taken as the radome of the microstrip antenna array, the homotactic magnetic conductivity can be adjusted to be zero by changing the distance between the printed circuit boards, and the obtained corresponding effective index is zero. The energy of electromagnetic wave emitted by the microstrip antenna array can be concentrated along the normal direction of the radome when the electromagnetic wave passes through the radome, thus achieving the effect of accumulating energy and improving the directional property and the gain of the whole antenna. The highly directional antenna can be applied to various wireless transmissions, beam communications and interferential emission and receiving systems such as communication, radar, etc. Compared with the traditional antenna, the system structure of the antenna has the advantages of simple and small structure, convenient disassembly and assembly, low cost, good directional property, high gain, etc.

Description

technical field [0001] The invention relates to an antenna of a transmitting and receiving system in the field of wireless communication, in particular to a high-direction antenna using a ring-shaped metal pair unit structure radome. Background technique [0002] With the rapid development of high and new technology, the core supporting role of electronic technology in military and civilian use is becoming more and more obvious. In particular, modern warfare has exacerbated the confrontation in the electromagnetic field. The battlefield situation is changing rapidly, and information exchanges are more frequent. It is necessary to ensure smooth communication at any time. Therefore, it is particularly important to have powerful anti-jamming communication and communication interference tools. In civilian use, mobile communication is a very popular technology application in today's society, and mobile phones have become an essential communication tool for people. [0003] In v...
