This paper introduces the design of a novel planar ultra-wideband filtering antenna. This new filter antenna has dual band notched characteristics in 5.5GHz and 7.5GHz. It consists of an ultra-wideband (UWB) filter and an antenna. In the filter, the E-shaped mode is used to realize the two transmission zeros and the double notch characteristics of the ultra-wideband pass filter. Dual stopband characteristics...
This paper presents a dual-band band-pass filter with a ring resonator and arrow-shaped defected ground structures (DGS). The two frequency bands are generated by the ring resonator and the two arrow-shaped defected ground structures are used to realize microstrip lines with high impedance to control the two frequency bands conveniently. In order to validate the simulation, a microstrip dual-band...
