Patch hybrid couplers are used to provide arbitrary power division ratio over two frequency bands. The coupler is designed using three main topologies. They are Branch-line, Coupled-line and Patch. Branch-line and Coupled-line provides equal power division ratio over two frequency bands. Patch structure provides arbitrary power division ratios. The patch hybrid coupler is the rapid development ...

a compact and sharp-rejection ultra-wideband (uwb) microstrip band-pass filter (bpf) is developed using of left handed metamaterials realized by complementary split ring resonator (csrr). moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. in comparison with some other filters, this structure shows a significantly wider passband due to...

An accurate equivalent circuit model for the microstrip line with a complementary split ring resonator (CSRR), and the parameter extraction method, are presented. A highpass filter with steep rejection is designed based on the model. The measurement results confirm the efficient analysis and design procedure and the validity of the highpass filter configuration. DOI: 10.2529/PIERS060906062902

In this paper, a two-dimensional (2D) displacement sensor based on the diagonal symmetry complementary split-ring resonator (CSRR) structure is proposed. The one-dimensional (1D) initially developed by etching ring ground plane, and triangle metal patch used as mover. When mover attached, CSRR formed, thereby inducing resonant frequency. of can be retrieved variation in Then, extended for desig...

A novel microstrip Coupler with Complementary SplitRing Resonator (CSRR) is simulated and fabricated. The CSRR structure in the grounded plane of a conventional microstrip double-line coupler, increases its even mode characteristic impedance. This results in a higher degree of coupling. The results of simulation and measurement show that the new coupler achieves a high degree of coupling (5 dB ...

This paper presents the electrically small U-slot loaded circular microstrip patch antenna with Complementary Split Ring Resonator (CSRR). The technique of U slot loading is used for operating antenna in dual band and CSRR technique to make antenna compact and CSRR for compactness is used. The simple circular patch antenna resonates at 5. 71 GHz with return loss of -11. 38 dB. The proposed ante...

This paper presents a novel compact dual-band and dual-polarized complementary split-ring resonator (CSRR)-fed substrate-integrated waveguide (SIW) cavity-backed fractal patch antenna for wireless energy harvesting and communication. The proposed antenna is composed of a Giuseppe Peano fractal radiation patch with a backed SIW cavity. To enhance the bandwidth and minimize the dimensions, the CS...

Three dual-mode band-pass filters are presented in the present paper. The first filter is realized by dual-mode substrate integrated waveguide (SIW) cavity; the second is based on the integration of SIW cavity with electromagnetic band gap (EBG); and the third is based on the integration of SIW cavity with complementary split ring resonator (CSRR). The dual-mode SIW cavity is designed to have a...

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...

A compact circularly polarized (CP) patch antenna using a composite right/left-handed (CRLH) transmission line (TL) unit-cell is proposed. The CRLH TL unitcell includes a complementary split ring resonator (CSRR) for shunt inductance and a gap loaded with a circularshaped slot for series capacitance. The CSRR can decrease the TM10 mode resonance frequency, thus reducing the electrical size of t...
