Notched UWB bandpass filter using complementary single split ring resonator

In this paper, a simple method to obtain a notch in the ultra-wideband (UWB) bandpass filter is presented. UWB bandpass filter is designed using ground plane aperture technique. To reject the undesired wireless local area network (WLAN) signals, a complementary single split ring resonator (CSSRR) is placed under the coupled lines of the bandpass filter. The CSSRR has flat insertion loss and goo...

Compact Varactor-Tuned Bandpass Filter Using Open Split-Ring Resonators

This paper presents a compact tunable bandpass filter that is based on open split ring resonator to achieve high out-of-band rejection. Exact equations and design procedures are given based on strict theoretical analysis. By loading the varactor diodes, the center frequency and bandwidth of the bandpass filter could realize reconfigurable. Then defected ground structure was adopted in the input...

Frequency Switching of PIFA Using Split Ring Resonator

In this paper, a PIFA loaded with split ring resonator (SRR) is presented, in which frequency switching is performed by varying the radius of split rings. The proposed Planar invertedF antenna (PIFA) without metamaterial resonates at 7.46 GHz with return loss of -23.71 dB, gain value 5.41 dBi and bandwidth 361.8 MHz. Proposed PIFA structures with metamaterial loading resonates at multiple frequ...
