High directional antenna using annular metal pair unit structure antenna cover

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.
