A multi-frequency high-gain microstrip slot antenna with double-layer dielectric substrate

Abstract

A double-layer dielectric substrate multi-frequency high-gain microstrip slot antenna, including two rectangular dielectric substrates stacked together, the upper surface of the upper dielectric substrate is provided with four right-angle triangular metal patches, and the four right-angle triangular metal patches They are equal in size and right-angled to form a rhombus structure. Counterclockwise, they are the first triangular patch, the second triangular patch, the third triangular patch and the fourth triangular patch, the first triangular patch and the third triangular patch The isosceles right-angled triangles of equal size are cut off at the right angles of the slices to form two trapezoidal structures; the upper surface of the upper dielectric substrate in the vertical gap is provided with a rectangular metal patch, and the lower surface of the lower dielectric substrate is covered with a metal grounding plate. A rectangular gap is set on the floor, corresponding to the tail of the rectangular metal patch, a circular via hole is opened through the lower dielectric substrate, and a circular feed port corresponding to the circular via hole is provided on the metal ground plate. The invention can realize multi-frequency resonance high-gain radiation.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a multi-frequency high-gain microstrip slot antenna with a double-layer dielectric substrate. Background technique [0002] While the rapid development of information technology has brought great convenience to human life, it is also changing people's traditional production and lifestyle.
