AbstractIn this paper, a novel single-cavity triangular substrate-integrated waveguide (TSIW) dual-band filter loading a complementary triangular split ring resonator (CTSRR) is proposed, which has three transmission zeros (TZs) in the stopband in total. The dual-band response is achieved by the CTSRR and the degenerate modes of the TSIW cavity. In order to control the TZs, we propose two adjustment techniques, shift feeding technique and adding via perturbation. In addition, the CTSRR etched on the surface can produce a new TZ in the upper first-passband. Finally, a dual-band filter with three TZs is simulated, fabricated, and measured. There is a good agreement between the simulated results and measured ones.

Substrate Integrated Waveguide (SIW) is a special antenna technology which retains reduced copper surface waves and low dielectric loss property of classical rectangular waveguides. The antennas developed on SIW have simple configuration with an ease of fabrication in flame redundant wearable and integration in walls and floors. In this sense a Quarter-mode SIW (QMSIW) antenna has been designed, analyzed and its performance has been compared with Half-mode SIW. QMSIW has been precisely designed to operate efficiently in the range of 40 - 57 GHz. It aims at enhancing the bandwidth for 5G applications with a maximum return loss of -36 db at 55 GHz. HMSIW structure has Triple band resonant frequencies at 20.5 GHz, 24.7 GHz & 27 GHz with the return loss values of -34 db, -14 db & -32.5 db respectively. Both antennas operate in 20 – 72 GHz range of 5G applications.
