Abstract

The invention relates to a wide band one-layer microstrip patch antenna, which solves the problem of narrow impedance width in the currently common microstrip antenna. The microstrip patch of the antenna is a one-layer microstrip patch; one end of a stair-stepping coplane microstrip line with two widths is inserted in the patch antenna by the open slot on a convex microstrip patch, and the other end of a feeding microstrip line is positioned at the edge of a microstrip dielectric-slab; a concave metal carinal cavity is arranged at the back surface of the microstrip dielectric-slab excluding the position corresponding to the microstrip patch and in the middle of structural mounting plate. The wide band one-layer microstrip patch antenna can form a large microstrip patch antenna array easily, which is in favor of impedance matching of the antenna, the subnetwork design for microstrip work, the weight reduction of the antenna and the bandwidth widening of the antenna; the wide band one-layer microstrip patch antenna of the invention has the advantages of simple and compact structure and small cross section, which improves the telecommunication performance and reduces the whole weightof the antenna array.

Description

technical field

[0001] The invention relates to an improved structure of a single-layer dielectric microstrip patch antenna, in particular to a wide-band, metal back cavity structure, thin single-layer dielectric convex microstrip patch antenna. The invention can be used both for receiving and for transmitting radio waves. Background technique

[0002] Broadband antennas are increasingly used in military and civilian applications. At the same time, in some specific applications, there are special requirements for the antenna array such as volume, weight, efficiency and environmental adaptability. For example: for aircraft / satellite platforms, antennas are required to have a thin profile, light weight, high efficiency and meet certain environmental application conditions.

[0003] There are many types of radiating antennas suitable for planar antenna arrays, mainly waveguide slot antenna arrays, printed dipoles, and microstrip patch antenna arrays. The waveguide slot anten...
