Problems solved by technology

In the traditional design, the general practice is to directly cascade them without changing the structural parameters of the filter. However, due to the reflection and mismatch existing in the filter unit and the patch antenna, it will greatly affect the performance of the integrated antenna system. performance

Embodiment Construction

[0021] The invention will be further illustrated by the following examples.

[0022] The specific embodiment of the present invention is as figure 1 with figure 2 shown.

[0023] An integrated ultra-wideband antenna integrated with a slot line ultra-wideband filter unit is composed of a branch-loaded slot line resonant unit and a hexagonal patch radiation unit cascaded. The hexagonal patch radiating unit is arranged on the front of the dielectric plate 4, and the branch-loaded slot line resonant unit is etched on the back of the dielectric plate 4; including the hexagonal patch radiating unit, the branch-loaded slot line resonant unit and the integrated ultra-wideband antenna The input port (hereinafter referred to as the input port) is composed of 3.

[0024] The hexagonal patch radiation unit is composed of a hexagonal patch main radiation unit (hereinafter referred to as the main radiation unit) 1 combining trapezoidal and rectangular shapes, and a gradient microstrip l...

Abstract

The invention discloses an integrated ultra wide band antenna of a fusion slot line ultra wide band filter unit. The integrated ultra wide band antenna of the fusion slot line ultra wide band filter unit is composed of a branch loading slot line resonant cell and a hexagonal paster radiation unit in a cascading mode. The hexagonal paster radiation unit is composed of a main hexagonal paster radiation unit and a gradual micro-strip line, wherein the main hexagonal paster radiation unit is composed of a trapezoid and a rectangle; the branch loading slot line resonant cell is composed of a U-shaped slot line resonant cell and three loaded slot line branches, wherein two ends of the U-shaped slot line resonant cell are connected with a stepped impedance cell, the three branches are uniformly distributed in a resonator, and the end of the middle branch is connected with a circular slot line paster. Compared with a traditional ultra wide band filter, the integrated ultra wide band antenna of the fusion slot line ultra wide band filter unit greatly improves the out-of-band rejection characteristic of the ultra wide band antenna based on guaranteeing the circuit volume, effectively reduces the reflection and consumption of the antenna in cascading, and enables the whole performance to be improved. The integrated ultra wide band antenna of the fusion slot line ultra wide band filter unit achieves the frequency selectivity of the ultra wide band without changing a feeder structure.

Description

technical field [0001] The invention belongs to the technical field of wireless communication and relates to an integrated ultra-wideband antenna. Background technique [0002] With the continuous development and progress of science and technology, ultra-wideband systems have attracted much attention because of their fast transmission speed and high security performance. As an important element in the system, UWB antenna has become a new research hotspot. According to the U.S. Communications Commission's regulations on the operating frequency range of ultra-wideband antennas, the standard frequency range is between 3.1 GHz and 10.6 GHz. However, among currently designed UWB antennas, the bandwidths of many antennas are not UWB antennas in the strict sense. In order to get the standard ultra-wideband range, because of its extremely wide frequency band coverage, adjustment will be relatively difficult, and it will also increase the complexity of the antenna. At the same tim...
