“…The substrate-integrated waveguide (SIW) technologies have been proposed to combine the advantages of rectangular waveguide and microstrip circuits [3,4]. Substrate-integrated folded waveguides (SIFW) and halfmode substrate-integrated waveguide (HMSIW) have been proposed to reduce the size of SIW in [5,6], respectively. The design of a miniaturized substrate-integrated waveguide using embedded split-ring resonators has been illustrated in [7,8].…”

A novel planar Yagi antenna printed on a microwave substrate with dielectric constant of 3.55 for Ku band applications has been presented in this paper. The proposed antenna has been fed by the slow-wave half-mode substrate-integrated waveguide and has achieved good characteristics, such as reduced size, high gain, broadband, and low insertion loss. The proposed antenna has been fabricated by Rogers 4350 substrate with lengths of two arms for dipole 0.46 λ 0 . Measured results indicate that the impedance bandwidth (below −10 dB return loss) is from 15.4 GHz to 19.4 GHz with peak gain 7.49 dBi. Both simulations and experiments convince that the proposed antenna could have reliable applications for Ku band wireless communications.

A novel double folded quarter mode substrate integrated waveguide (DFQMSIW) resonator is proposed. The dominant resonant mode of the proposed resonator is TE 101 mode. The size of the DFQMSIW cavity is reduced nearly by 94% compared with the conventional SIW cavity. A three order cascaded DFQMSIW filter with a center frequency of 2.84 GHz and a fractional bandwidth of 11.5% is implemented. The measured results show that the filter insertion losses are below −1.8 dB and return losses are better than −15 dB. Good agreement between simulated and measured results demonstrates the validity of the proposed method.

“…In recent years, with the rapid development of microwave and millimeter communications systems, the substrate integrated waveguide technology [1] has attracted many people attention owing to its low cost and completed planar structure, some high quality microwave and millimeter devices have also been proposed [2,3,4,5,6,7,8,9,10]. In these literatures, there have been only a limited number of active circuits described [11,12], since the design of both mechanical support and dc bias are a big challenge in active waveguide circuits based on SIW and related technology.…”

In this letter, a broadband coupler is presented that makes use of a corrugated half mode substrate integrated waveguide (CHMSIW) technique using a printed circuit board process. The coupler is realized by parallel CHMSIW lines where the vias to form the sidewalls of the HMSIW are placed with the open-circuit quarter-wave-length microstrip stubs and the energy couples by magnetic field. Compared with conventional SIW coupler, it is easily integrated with active devices because it can isolate better the CHMSIW input/output ports from the ground plane. The coupler is simulated and measured at 9.5-17.5 GHz. The result of measurement shows a good agreement with the result of simulation.
