This article introduces analysis of the new configuration; inductor loaded left‐handed composite right‐/left‐handed transmission line ((L‐CRLH TL). Compared to conventional CRLH and dual CRLH, this configuration has the advantage of very slow phase (almost constant) and nonlinear propagation coefficient which enables it to be very effective in designing compact size and ultra‐wideband (UWB) microwave...
In this paper, compact size band pass filters are proposed and designed for WLAN applications. The coupled DGS resonators are considered the main block of proposed band pass filters. The three proposed filters are designed by using the same defected ground structure shape, but with different feed line configurations. The feed line configuration affects the presence of transmission zeros in the rejection...
A four-way ultra-compact power divider is proposed in this paper for antenna array applications. The power divider is constructed based on composite right/left handed microstrip structure. The analytical analysis are presented. The divider operates at 5.2 GHz for WLAN services. This paper introduces equivalent circuit, 3D full wave simulation, and in addition to that, this design realizes compactness...
This paper represents an ultra-compact quad band resonator based on novel configuration of dual-composite right/left handed transmission line. This design broaches quad band for 7.3 GHz, 8.3 GHz, 11.9 GHz, and 13.8 GHz along with insertion losses of 2.2 dB, 0.27 dB, 2 dB, and 1.5 dB, respectively. Furthermore, the return losses are 12.2 dB, 36 dB, 20.5 dB, and 19.5 dB, respectively. The quality factor...
A new compact multiband resonator based on one modified cell of dual-composite right/left-handed microstrip structure is presented in this paper.

Moreover, the return losses are equal 13 dB, 43 dB, and 10 dB, respectively. The paper elaborates the equivalent...
A compact dual ultra-wide band power dividers based on three cells of dual composite right/left handed microstrip structure presented in this article. This introduced topology proposes dual band for multiband orthogonal frequency division multiplexing from 1 GHz–4.8 GHz with insertion loss −5 dB for three way power divider. The second band designed for direct sequence ultra-wideband from 6.2 GHz–9...
A compact ultra wide band impedances transformer based on new configuration of composite right/left handed transmission line is presented. The proposed design introduces ultra wide band pass frequencies extended from 2 GHz up to 11 GHz with perfect matching transmission coefficient. However, the whole topology is designed using new loaded inductor configuration of CRLH. This L-CRLH is implemented...
This paper presents, for the first time, a coupled gap transmission line resonator based on dual composite right/left handed microstrip structure. This introduced topology proposes dual band with high selective sharp band pass response. The whole structure is designed using only one cell comprised using a shunt tank of interdigital capacitor and strip inductor, and series tank formed using patch capacitor...
