“…SIW is typically fed by a microstrip [8][9][10][11][12], however, for a thick substrate, a 50 Ω microstrip feed line will be very wide and would excite higher order modes with the potential to radiate. As an alternative, we have developed a grounded coplanar waveguide (GCPW) feed for a smoother transition [13,14].…”

“…Various SIW power dividers have been studied like in [1,3], and [4] and relatively good results have been already reported. For example, Hao et al in [1,4] utilized a SIW binary feed network that showed an improved performance, but its 2.5 dB insertion loss is still relatively high and does not cover the entire X-band frequency range (8)(9)(10)(11)(12). Similarly, Yang et al [5] developed an 8 way SIW power divider, but its insertion loss is also relatively high (2.5 dB) over 9-11 GHz frequency band, but definitely there is still a room for further development.…”

Abstract-Ultra wideband components have been developed using SIW technology. The various newly developed components include a GCPW transition, Y and T-junctions. The GCPW transition covers over 10 GHz bandwidth with less than 0.4 dB insertion loss. The optimized T and Y-junctions have relatively wide bandwidths of greater than 40% that have less than 0.6 dB insertion loss. The developed transition was utilized to design an X-band eight-way power divider that demonstrated excellent performance over a 4 GHz bandwidth with less than ±4 • and ±0.9 dB phase and amplitude imbalance, respectively. Theoretical and experimental results are presented and compared with previously designed SIW power dividers. The developed SIW power divider has a low profile and is particularly suitable for circuits' integration.

Abstract-The design and simplified analysis of a compact and wide band (16%) negative permittivity complementary split ring resonator metamaterial is introduced. The proposed metamaterial component was applied to reduce the size of the feeding line filter of microstrip patch antenna for the sake of higher order harmonic suppression. The reduction has been done using only one element of complementary split ring resonator, while maintaining the antenna's performance. Simplified theoretical study and design of the proposed circuits has been presented. Moreover, experimental results have been done for validation and conformation purpose. Results confirm that almost 95% of the antenna noise harmonics power has been removed.

Abstract-A new super compact ultra-wideband (UWB) bandpass filter (BPF) with triple-notched bands is presented in this paper. Firstly, a new square ring quad-mode resonator (SRQMR) is employed to obtain the initial UWB BPF. Then, a triple-mode stepped impedance resonator (SIR) is inserted into the initial UWB BPF to achieve three desired notched bands. The proposed triple-mode SIR is found to have the advantages of introducing triple-notched bands and provide a higher degree of freedom to adjust the resonant frequencies. To validate the design concept, a new super compact UWB BPF with triple-notched bands respectively centered at frequencies of 3.7 GHz, 5.2 GHz and 7.8 GHz is designed and measured. The predicted results are compared with measured data, and good agreement is reported.
