Abstract
The invention discloses a high-gain substrate integrated leaky-wave antenna based on a TE30 mode. The high-gain substrate integrated leaky-wave antenna comprises an upper-layer metal plate, a dielectric substrate and a metal floor, wherein the upper metal plate is arranged at the top of the dielectric substrate, and rectangular gap arrays are arranged on two opposite sides of the upper metal plate; the metal floor is arranged at the bottom of the dielectric substrate; the dielectric substrate is provided with a plurality of short-circuit via holes penetrating through the upper metal plate andthe metal floor; the plurality of short-circuit via holes are arranged in two rows; the two rows of short-circuit via holes are respectively positioned on two sides of the dielectric substrate and arepositioned on the outer sides of the rectangular gap arrays; microstrip lines connected with the upper-layer metal plate are arranged at the two ends of the upper-layer metal plate, and the microstrip lines are used for feeding. The antenna has the advantages of low profile and high gain, and the beam can be scanned to end-fire.
Description
technical field [0001] The present invention relates to the technical field of communication antennas, and more specifically, to a TE-based 30 Modular high-gain substrate-integrated leaky-wave antenna. Background technique [0002] At present, most of the chip-integrated leaky-wave antennas work in TE 10 mold. Based on TE 10 The transverse groove substrate integrated leaky-wave antenna of the model is a quasi-uniform leaky-wave antenna, so the beam can be scanned from the direction close to the edge-fire to the end-fire direction. It has the characteristics of simple feeding, low profile, and can be scanned to the end-fire. Gain is lower when not scanned to endfire. [0003] Existing TE-based 20 The beam of the substrate-integrated periodic leaky-wave antenna of the mode can be scanned from backward to forward, which is used to improve the radiation performance of the antenna; and based on TE 20 A substrate-integrated leaky-wave antenna modulating longitudinal slots, d...
