“…Figure A shows the proposed MTM unit cell. The suggested subwavelength MTM is based on an initial symmetrical split ring resonator DGS layout, which is designed and characterized as a lowpass filter . This MTM structure is implemented by etching the double slit complementary split ring resonator (DS‐CSRR) on a microstrip line ground plane.…”

A wideband epsilon-negative structure is employed as one-layer and two-layer isolators to reduce mutual coupling in multiple-input multiple-output systems composed of two E-coupled rectangular dielectric resonator antennas. The proposed unit cell with −15 dB bandwidth for S 21 extending from 1970 to 3317 MHz, is a double slit complementary split ring resonator etched on the ground plane of a stripline. Each layer is composed of a 2 × 3 array of the suggested unit cell. Reduction in isolation of more than 11 dB for the one-layer case and higher than 20 dB for the two-layer case are measured within the frequency range of 2.604 to 2.64 GHz which includes WiMAX. The highest isolation level of 36 dB is realized at 2.868 GHz. The impedance matching, gain, radiation efficiency, and envelope correlation are improved compared to the original case. A prototype is designed, fabricated, and tested. Simulation data and measurement results are in good agreement.

“…Moreover because of the use of via it requires the extra fabrication processing steps for drilling and soldering as compared to the proposed UWB BPF. The UWB bandpass filter presented in [4] is based on defected ground structure (DGS) as split ring resonator and conventional CRLH TL with via. The reported filter [4] is compact in size, 13 x 8.5 mm 2 , however because of the split ring resonator structure in ground plane and the presence on via, it requires the more extra efforts in ground plane processing and for creation of via.…”

“…Thus, size reduction is one of the major issues in the design of UWB BPF. The researches on length reduction of UWB BPF have been reported in [7–12]. In [7], a compact UWB band‐pass filter (BPF) using a dual stub loaded resonator (DSLR) is presented.…”
