LTCCC laminated wideband microstrip staggered triangle array antenna

Abstract

The invention belongs to the technical field of antennas, and provides an LTCC laminated wideband microstrip staggered triangle array antenna. The LTCC laminated wideband microstrip staggered triangle array antenna is used for overcoming the disadvantages of an existing microstrip patch antenna in the aspects of giving consideration to high gain, wide frequency band and miniaturization. The antenna comprises an upper radiation metal patch antenna array, a lower radiation metal patch antenna array, an upper dielectric substrate, a lower dielectric substrate, a welding hole, a feed network, a grounding metal layer and a coaxial connector probe, and is characterized in that the upper dielectric substrate, the lower dielectric substrate and the grounding metal layer are respectively in the shapes of rectangles with teeth; the upper metal patch antenna array and the lower metal patch antenna array are respectively composed of upper unit metal patches and lower unit metal patches in the arrangement of staggered triangles; and the upper unit metal patches and the lower unit metal patches are respectively in the shapes of rectangles provided with semi-U-shaped grooves. The LTCC laminated wideband microstrip staggered triangle array antenna provided by the invention can well give the consideration to the performance requirements of the microstrip patch antenna such as high gain, wide frequency band and miniaturization, and is relatively simple in structure.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to an LTCC stacked broadband microstrip interleaved triangular array antenna. Background technique [0002] Since the microstrip antenna theory has been widely studied in the 1970s and has achieved great development, it has become more and more popular because of its advantages such as light weight, low profile, small size, easy to conform to the carrier, and simple structure. , have been used more and more in the fields of airborne, spaceborne, missile-borne antennas, medical microwaves and civil communications. In the current navigation and communication system, the microstrip antenna accounts for almost half of it; however, the frequency band of the microstrip patch antenna is very narrow. The current common ways to solve this problem include using thick substrates or stepped substrates, reducing the dielectric constant of the substrate, increasing the Large substrate loss tang...

Problems solved by technology

In the current navigation and communication system, the microstrip antenna accounts for almost half of it; however, the frequency band of the microstrip patch antenna is very narrow. The current common ways to solve this problem include using thick substrates or stepped substrates, reducing the dielectric constant of the substrate, increasing the Large substrate loss tangent, multi-layer structure, additional impedance matching or passive patch, etc.; but these methods are at the expense of increasing the thickness or area of ​​the antenna, which is not conducive to the conformal shape of the microstrip patch antenna and the carrier and miniaturization development requirements, making the antenna structure complex, unable to take into account the antenna broadband and miniaturization requirements
