Abstract

The invention discloses an all solid-state plasma near coupling cloaking antenna array and a control method thereof. The all solid-state plasma near coupling cloaking antenna array comprises solid-state plasma antenna units, an upper layer dielectric substrate, a micro-strip coupling feeder line, a bottom layer dielectric substrate and a grounding metal plate. The solid-state plasma antenna units comprise semiconductor plasma units, plasma unit control chips, line control wires and queue control wires. All the plasma units are controlled independently through a peripheral control circuit, the plasma antenna units of different shapes are formed, and reconstruction of an antenna structure is achieved. The antenna structure is compact and simple, the cost is low, the antenna structure can work in a 1 GHz-100GHz wave band, the limitation that a traditional gas plasma antenna can not work in a high frequency band easily is broken through, and the advantages of being capable of achieving beam scanning, good in cloaking performance and the like are achieved.

Description

technical field [0001] The invention relates to the field of antenna and semiconductor technology, in particular to an all-solid-state plasma proximity coupling stealth antenna array. Background technique [0002] In modern high-tech warfare, radar systems and communication systems are crucial to the outcome of the war. As a key component of the radar system and communication system, the performance of the antenna has a crucial impact on the system; at the same time, due to the large radar cross section (RCS) of the antenna, it is also very easy to become a prominent target for the enemy to discover and attack. Therefore, it is of great significance to improve the performance index (including the stealth performance) of the antenna. [0003] For traditional antennas, in order to achieve the best transmission and reception effects, it is usually impossible to adopt conventional methods such as shape and coating of absorbing materials for stealth, so the RCS of the antenna is...
