BAND-NOTCHED ULTRA-WIDEBAND ANTENNA
(2013-07-25)
Chung Shyh-Jong

Chuang Chao-Tang
A band-notched ultra-wideband antenna comprises a top layer non-uniform short-circuit metal patch, a middle layer metal radiation patch, and a bottom layer metal patch. The bottom layer metal patch includes a coupled open/short circuit stub which is set close to the middle layer metal radiation patch. The equivalent circuit of the top layer non-uniform short-circuit metal patch is a parallel LC resonator, and the equivalent circuit of the coupled open/short circuit stub is a series LC resonator. The resonant frequency of the top layer non-uniform short-circuit metal patch is equivalent to the resonant frequency of the coupled open/short circuit stub, so as to function as a second-order bandstop filter to yield high notch-band-edge selectivity without increasing total circuit area of the band-notched ultra-wideband antenna.

An electromagnetic band-gap structure includes a circuit board, a ground plane and a plurality of electromagnetic band-gap units. The circuit board includes a first side and a second surface, and the ground plane disposed on the first side. The plurality of electromagnetic band-gap units are located on both the first surface and the second surface and connected to each other along an edge of the ground plane. Every electromagnetic band-gap unit includes a first strip line, a second strip line and a via. The first strip line is located on the first side, including a first relative long strip line and a first relative short strip line connected to the ground. The second strip line is located on the second side. The second strip line is connected to the first strip line of the adjacent electromagnetic band-gap unit through the via.

A printed filtering antenna is provided. This filtering antenna comprises an antenna part and a coupled line resonator. The antenna part is directly connected to a coupled line resonator and occupies an antenna area. The coupled line resonator provides a filtering mechanism together with the antenna part. The coupled line resonator comprises a short-circuited stub and an open-circuited stub. The short-circuited stub comprises an open-circuited end and a short-circuited end connected to ground. The open-circuited stub is parallel to the short-circuited stub. The open-circuited stub comprises a first end and a second end. The first end is connected to the feed point and is corresponding to the open-circuited end of the short-circuited stub such that the open-circuited stub is coupled to the short-circuited stub.
