Problems solved by technology

[0003] The impact of antenna mutual coupling on various wireless communication and detection systems cannot be underestimated. Mutual coupling will deteriorate the isolation between transceivers, reduce system capacity, introduce scanning blind spots, and affect system design accuracy.
In the continuous wave detection system, the deterioration of the channel isolation caused by the mutual coupling between the transmitting a

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a small spacing microstrip antenna array comprising a dielectric substrate which is provided with a first surface and a second surface which are opposite to each other; a firstmicrostrip antenna and a second microstrip antenna which are arranged on the first surface of the dielectric substrate and spaced relative to each other in a first direction; and a resonant decoupling unit which comprises an open resonant ring formed by a microstrip line, wherein the open resonant ring is arranged on the first surface of the dielectric substrate and positioned between the first microstrip antenna and the second microstrip antenna. The coupling of the small spacing microstrip antenna can be suppressed.

Description

technical field [0001] The invention relates to the technical field of antenna coupling, in particular to a small-pitch microstrip antenna array. Background technique [0002] As a transceiver device for radio signals, antennas have become an indispensable part of wireless systems and are used in various fields such as mobile communications, radio and television, radar detection, satellite navigation, and deep space exploration. In many practical applications, antennas usually appear in pairs in transceiver wireless systems (such as radio frequency identification systems, continuous wave detection systems, etc.), or appear as array elements in multi-element antenna arrays (such as adaptive antenna arrays, multiple-input Output antenna array and phased array, etc.), or appear as a functional unit in a multifunctional wireless terminal device (such as a notebook computer, a mobile phone, etc.). In these cases, coupling between adjacent antenna elements is unavoidable, and thi...
