Abstract

Disclosed are a microstrip antenna and a television. The microstrip antenna comprises a substrate, the substrate comprising a first surface and a second surface provided opposite the first surface. The microstrip antenna further comprises a feed portion, a ground layer and an antenna portion, wherein the feed portion is provided on the first surface of the substrate; the ground layer is provided on the second surface of the substrate; the antenna portion is provided on the first surface of the substrate; the antenna portion is rectangularly provided; a long side of the antenna portion is provided with two rectangular grooves parallel to short sides; the long side, provided with the rectangular grooves, of the antenna portion is electrically connected to the ground layer by means of multiple metal through holes; and the antenna portion comprises a connecting segment located between the two rectangular grooves, the connecting segment being electrically connected to the feed portion.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a microstrip antenna and a television. Background technique [0002] The general microstrip antenna is to apply metal foil on the back of the dielectric substrate as the ground plane, and use photolithography and etching technology to make a metal patch of a certain shape (microstrip antenna) on the front. The common ones are rectangular and circular. A planar antenna composed of a wire or a microstrip line fed to a patch is also called a microstrip antenna. The working principle of the microstrip antenna is that the metal patch is equivalent to an inductance-capacitance resonant circuit. The electromagnetic wave fed through the coaxial line generates electromagnetic resonance in the metal patch, and finally radiates or receives the electromagnetic wave energy. [0003] The microstrip antenna is characterized by thin profile, small size, light weight, low cost, easy to mass-pro...
