Embodiment Construction

[0019] The invention designs a reconfiguration patch UWB filter based on multi-mode resonance, the filter can generate ultra-wide band, and multi-mode appears in the pass band, the structure is simple, the size is small, and miniaturization is realized.

[0020] The invention will be described in more detail below in conjunction with the accompanying drawings:

[0021] An example of the present invention is figure 2 As shown, the dielectric substrate (104) is FR4_epoxy with a dielectric constant of 4.4. The size of the dielectric substrate meets the specification requirements, the thickness of the dielectric substrate is 1.59mm, and the dielectric loss is 0.02. The metal grounding plate (105) under the dielectric substrate is made of copper material.

[0022] Such as figure 1 As shown, the reconstruction patch UWB filter based on multi-mode resonance of the present invention, the reconstruction patch on the dielectric substrate is a low-impedance patch (1011), a low-impeda...

Abstract

The invention discloses a multimode resonance based reconstructed paster UWB filter. The filter is composed of a reconstructed paster (101) arranged on the upper surface of a medium substrate, port pasters (102), micro-strip transmission wires (103), the medium substrate (104) and a metal grounding board (105) below the medium substrate. According to the invention, the reconstructed paster is utilized for realizing the UWB-to-multimode filter. The filter provided by the invention is simple and compact in structure, small in size, convenient for processing, high in implementability, low in cost, ultra wide in band width and multiple in mode number. The multimode resonance based reconstructed paster UWB filter provided by the invention has in-pass band selection features. The selectivity is good. The multimode resonance based reconstructed paster UWB filter has high practical value.

Description

technical field [0001] The invention relates to a reconstruction patch UWB filter based on multi-mode resonance. The filter has multi-modes in UWB, realizes bandpass in UWB, and can well select signals in ultra-wideband, ultra-wideband (UWB) Bandpass filters have important practical value in wireless communication technology and radar systems as well as ultra-wideband positioning. Background technique [0002] The band-pass filter can pass the signal in the pass band well, and filter out the signal outside the pass band to realize the selective characteristics of the band-pass filter. However, with the continuous development of modern communication technology, the bandwidth of the required signal is getting wider and wider. At this time, the requirements for ultra-wideband are getting higher and higher. practical value. [0003] UWB or broadband microwave filters are very basic components of modern communication technology applications, such as UWB, radar systems, position...
