“…[9]. The first left-handed transmission line based on CSRRs was implemented by etching series capacitive gaps in the conductor strip, above the positions occupied by the CSRRs [10] where the series capacitive gaps are responsible for negative effective permeability. Thus, by combining these elements (gaps and CSRRs) at the resonance frequency of the resonators a lefthanded behavior is achieved in that band.…”

In the present work, we propose a voltage control oscillator (VCO) at high frequency consists of nonlinear composite right/left-handed transmission line (CRLH-TL) loaded with Resonant Tunneling Diode (RTD). We designed three prototype device examples. The first one consists of one cell with short circuit at the beginning of the cell between ground and patch, and 50 Ω load resistance were added at the end of the cell between ground and patch. The second one is similar to the first prototype but with open circuit at the beginning of the cell instated of short circuit. The third prototype consists of one cell with two 50 Ω load resistances added between ground and patch at the beginning and at the end of the cell. The proposed VCO models are capable of generating oscillations at frequencies between 4

“…The CR/LH TL have built in properties of being wideband and low-loss [26] and possibly have wide range of applications. M.Gil et al in 2007 proposed a wideband band pass filter using CR/LH TLs [27]. In this, complementary split rings resonators (CSRRs) and capacitive gaps edged on the top plane of the substrate are used.…”

In this work, a review has been presented on filter designs based on microstrip technology with the implementation of metamaterials. It briefly describes the properties of various types of resonators that behave as Left handed materials. Some of the implications of SRRs, CSRRs and other structures in filter design have also been discussed. General TermsMetamaterials in microstrip filters. KeywordsMetamaterials, microstrip filter, split ring resonator, complementary split ring resonator.

“…A composite UWB filter was designed by Menzel et al [3] by combining low-pass and high-pass filters as a suspended stripline structure with different planes. Presently, we take a different design method hinted by the metamaterial concept of CRLH-TL to reduce the filter size [4][5][6][7][8][9][10][11]. Reference 5 shows filters as periodic CRLH-TLs.…”

-The design of a new compact UWB bandpass filter is proposed, which has cascaded center-tapped microstrip composite right/left-handed transmission-line zeroth-order resonators (CRLH-TL ZORs). In an attempt to reduce the size, instead of the conventional half-wavelength resonators or periodic and multiple CRLH-TL cells, only one cell ZOR geometry is adopted as each resonator in the filter. Additionally, two center-tapped ZORs are coupled to increase the slope of the skirt. Besides, stepped impedance matching parts are placed in the paths to the input and output ports to enhance passband and stopband performances. The proposed filter is shown to have the overall size of 0.69 g λ × 0.70 g λ , the insertion loss much less than 1 dB, and an acceptable return loss performance in the predicted and measured results.
