Embodiment Construction

[0018] 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 some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0019] It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", et...

Abstract

The embodiment of the invention discloses an omnidirectional high-gain antenna based on meta-material. The omnidirectional high-gain antenna comprises an upper copper foil substrate and a circuit board supporting the upper copper foil substrate. The upper copper foil substrate is composed of multiple strip lines. Each strip line is composed of an upper grounding plate, a lower grounding plate anda metal conduction band. The upper grounding plate is printed on the upper copper foil substrate. The lower grounding plate is embedded in the circuit board. The metal conduction band connects the upper grounding plate and the lower grounding plate. The length of the metal conduction band is greater than half of the length of the upper grounding plate and greater than one third of the length of the lower grounding plate. The circuit board is provided with multiple metalized via holes for piercing of the adjacent metal conduction bands. The consistency and the stability of the antenna can be increased, the assembling process is simple and batch production can be facilitated, and series feeding is performed through multiple alternate feed strip lines so as to have high gain and great omnidirectional radiation characteristic.

Description

technical field [0001] The invention relates to the technical field of printed antennas, in particular to an omnidirectional high-gain antenna based on metamaterials. Background technique [0002] An omnidirectional antenna refers to an antenna that covers 360 degrees in azimuth. A high-gain omnidirectional antenna generally refers to an omnidirectional antenna with a maximum gain of more than 3dBi. [0003] Existing high-gain omnidirectional antennas usually use a number of omnidirectional antenna elements in the longitudinal direction to form a linear array to achieve a high gain effect. [0004] The feeding methods of high-gain omnidirectional antennas widely used at home and abroad are mainly divided into two types: series feeding and parallel feeding. Parallel-fed omnidirectional antennas require an additional feed network in addition to multiple antenna elements to achieve wider impedance matching, but the existence of the feed network often affects the out-of-roundn...
