Abstract

The invention relates to an ultra-wideband monopole antenna with trap characteristics, which comprises a dielectric substrate [1]; a metal grounding plate [2] is printed on one side of the dielectric substrate [1], and a radiation unit [3] and a feed unit [5] are printed on the other side of the dielectric substrate [1]; the antenna is characterized in that: a. the radiation unit [3] is in a regular hexagon shape, and a C-shaped groove [4] is carved on lower positions of the circle center of the radiation unit [3], and the C-shaped groove [4] is an open ring; b. the radiation unit [3] is directly connected with the feed unit [5]; and c. the metal grounding plate [2] is a ladder-shaped metal patch. The ultra-wideband monopole antenna with trap characteristics has good ultra-wideband and trap characteristics, and can eliminate the mutual impact with other narrow-band wireless communication systems; the trap is adjustable and can satisfy the application of special occasions; and the antenna has the advantages of small size, light weight, low consumption and simple structure, is applicable to mobile miniature equipment, meets the plane design requirements, facilitates the integration with an active circuit, has low cost, high precision and good repeatability, and can well designed conformally with equipment in the similar regular hexagon shape.

Description

Technical field:

[0001] The invention belongs to the technical field of antennas, in particular to the structure and grounding form of antenna radiation units. Background technique

[0002] Ultra-Wide Band (UWB) wireless communication technology has the advantages of simple system structure, high data transmission rate, low power consumption, high security, and strong multipath resolution ability. On February 14, 2002, UWB technology was first approved by the US Federal Communications Commission (FCC) for civil communication, and the 3.1-10.6GHz frequency band was officially opened to UWB for indoor communication, which has aroused widespread interest in countries all over the world. focus on. UWB is especially suitable for high-speed wireless access and military communication applications in dense multipath places such as indoors.

[0003] UWB antenna technology is one of the key technologies for UWB wireless communication. Conventional UWB antennas mainly include ridged...
