Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the o...

Abstract

The invention relates to a high-manufacturability trigram-type element metamaterial coating type microstrip antenna and a design method thereof. The antenna comprises a metal grounding plate, the metal grounding plate is attached to the lower surface of a microstrip antenna dielectric substrate, a microstrip antenna radiation patch is attached to the upper surface of the microstrip antenna dielectric substrate, the coaxial cable penetrates through the microstrip antenna dielectric substrate and is connected with the microstrip antenna radiation patch and the metal grounding plate, the cladding substrate is arranged at the half-wavelength position above the microstrip antenna dielectric substrate, the microstrip antenna dielectric substrate is connected with the cladding substrate through a supporting column, and the trigram-type metamaterial structure is attached to the upper surface of the coating substrate. The trigram-type metamaterial structure provided by the invention has an electromagnetic super characteristic, and can generate resonance with the radiation patch of the antenna to improve the gain performance of the antenna.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a hexagram-shaped primitive metamaterial-coated microstrip antenna with high preparability. Background technique [0002] Compared with other microwave antennas, microstrip antennas have the advantages of miniaturization, low profile, conformability, and easy integration. However, topology optimization of metamaterial microstrip antennas usually results in complex configurations, which brings great challenges to processing and preparation. Difficulties. The metamaterial cladding microstrip antenna is to place the metamaterial element on the cladding substrate above the radiation direction of the antenna, which increases the possibility of metamaterial layout and provides more possibilities for improving the performance of the antenna. Gain, increased bandwidth, beam switching, etc. have been widely used. However, the antenna design method that places the hexagram...
