The invention discloses a bilateral periodic short-circuit pin microstrip leaky-wave antenna with grounding plate slots. The bilateral periodic short-circuit pin microstrip leaky-wave antenna comprises a microstrip leaky-wave antenna body and periodic short circuit pins; the microstrip leaky-wave antenna body comprises a patch layer, a dielectric layer and a metal grounding plate which are sequentially arranged from top to bottom; the short circuit pins penetrate through the dielectric layer from top to bottom and are periodically distributed; and the grounding plate slots are formed in the metal grounding plate and are periodically distributed. According to the bilateral periodic short-circuit pin microstrip leaky-wave antenna with the grounding plate slots, the periodic short circuit pins are loaded on two sides, so that the forward-backward scanning of the main beam of the antenna is achieved, and the frequency sweeping range of the antenna is increased; and the grounding plate is periodically slotted, so that a new scanning angle is provided for the antenna in a lower space, and the beam scanning range of the antenna is enlarged.
Description
technical field [0001] The invention relates to the field of radio technology, in particular to a double-sided periodic short-circuit nail microstrip leaky-wave antenna with floor slots. Background technique [0002] Due to their inherent frequency-sweeping properties, leaky-wave antennas are favored in modern communication applications. Microstrip leaky-wave antennas have attracted a lot of attention because of their low profile, simple feed structure, and ease of fabrication. However, periodic leaky-wave antennas are generally designed for the upper space of the antenna, so they can only scan the upper space; and due to the influence of Open Stop-Band (OSB), periodic leaky-wave antennas usually do not have beam, so that its beam scanning range is limited, and it cannot be used in communication scenarios that require a larger beam scanning range; in addition, the methods to realize the antenna main beam scanning forward and backward in the upper space mainly include antenn...
