Embodiment Construction
[0022] The invention designs a novel double-stop-band UWB antenna, and the filter can avoid mutual interference with a WLAN system and a WiMAX system.
[0023] Below in conjunction with accompanying drawing, invention is described in more detail:
[0024] Such as figure 1 As shown, a novel dual stopband UWB antenna of the present invention, the radiation unit (101) on the dielectric substrate, the impedance matching input microstrip line (102), and the DGS structure (103) are made of copper material.
[0025] An example of the present invention is figure 2 As shown, the dielectric substrate (106) is FR4 material with a dielectric constant of 4.4, and the thickness of the dielectric substrate is 1.6mm.
[0026] The metal ground plate under the dielectric substrate is made of copper material.
[0027] Such as figure 2 As shown, the lengths of Rh, h1, h2, h3, f1, and f2 are 10mm, 14mm, 4mm, 12mm, 10mm, and 3mm respectively; image 3 As shown, the lengths of G, Wd, Ld, L1, ...
