Abstract

The present invention provides a reconfigurable slot antenna based on a sickle-shaped structure. The reconfigurable slot antenna based on a sickle-shaped structure of the present invention comprises a substrate and a metal plate attached to the upper surface of the substrate. Two horizontally symmetrical sickle-shaped slots are etched on the metal plate. Each sickle-shaped slot comprises a diode. By implementing the present invention, without changing the polarization mode, the frequency and the radiation directional diagram of an antenna are timely changed according to communication requirements, so that the spatial noise of a wireless communication system is reduced, electronic interference is avoided, system security is improved, and the channel capacity is increased.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a reconfigurable slot antenna based on a sickle structure. Background technique [0002] In recent years, with the rapid development and wide application of satellite navigation and satellite communication, antennas are the front-end equipment of these systems, and their performance indicators play an extremely important role in the performance of satellite communication handheld terminals and radio frequency identification card readers. effect. In addition, in order to facilitate the large-scale popularization and application of satellite communication terminals and radio frequency identification systems, the economic cost and volume of the system are crucial considerations. Under the premise, it must have the characteristics of low cost, compact structure and small size. When feeding an antenna or an array antenna, it is necessary to design the feeding network...
