“…The divider is extremely compact and its measured back-to-back insertion loss from 7.5 to 8.5 GHz is less than 2.5 dB This insertion loss is much lower than similar measurements reported by [14,15]. As mentioned in [18], this type of SIW feeding network can provide a balanced power division over a wide band. Both the balanced power split and low insertion loss should assist with increasing the gain and overall efficiency of the antenna array.…”

“…Alternatively (as shown in Figure 2(b)), Patrovsky et al [18] proposed a CPWG to SIW transition using an E-field coupling. The coupling slots are cut on the top surface of the SIW and placed next to the short circuit termination of the SIW.…”

“…Additionally, in the previous implementation of this transition [18,19], an SMA connector was utilized and no design details were given. However, in this case, due to the use of a thicker substrate to reduce the feed network losses, the employment of regular SMA connectors at the input feed port would not be practical.…”

Abstract-A compact Vivaldi antenna array printed on thick substrate and fed by a Substrate Integrated Waveguides (SIW) structure has been developed. The antenna array utilizes a compact SIW binary divider to significantly minimize the feed structure insertion losses. The low-loss SIW binary divider has a common novel Grounded Coplanar Waveguide (GCPW) feed to provide a wideband transition to the SIW and to sustain a good input match while preventing higher order modes excitation. The antenna array was designed, fabricated, and thoroughly investigated. Detailed simulations of the antenna and its feed, in addition to its relevant measurements, will be presented in this paper.

“…The PGL lines have already been characterized for higher frequencies by means of transitions: PGL to 50 Ω microstrip line circuit transitions on ceramic substrate (0.254 mm alumina), dedicated to feed PGL loads and power divider/combiner, present, for a 16 mm total length of the back-to-back structure, a 4 dB transmission parameter from 40 GHz to 60 GHz [12], or dedicated to feed couplers with short range (60 GHz) radio [13], a coplanar-Goubau Line transition on Duroid 5880 provides a 5-10 dB insertion loss and a return loss better than −12 dB from 140 GHz to 220 GHz for a back-to-back structure [14] and recently a "smooth" transition to match a periodic leaky-wave antenna at millimeter wave frequencies with PGL impedance to a coplanar waveguide [15]. The results for the transitions to excite the PGL mode [12][13][14][15] seem less efficiency than for the other ones [2][3][4][5][6][7][8][9][10][11]: the PGL doesn't need a ground plane, contrary to the coplanar or micro-strip modes and the conversion from coplanar or micro-strip modes to PGL mode generates other modes or losses.…”

Abstract-We present Coplanar-Planar Goubau Line (PGL) transitions designed on high-resistivity Silicon to characterize a PGL using microwave probing. These transitions are optimized in the 57-64 GHz frequency band to present excellent electrical performances despite the field disturbance of the measurement setup. As the transitions are positioned on a probe station chuck, a glass substrate is added between the transition under test and the metallic chuck to minimize the disturbance. 3-D fullwave electromagnetic field simulations performed on a commercial software and on-wafer measurements show almost comparable results in term of scattering matrix parameters. Low losses are attained with a measured average transmission parameter of 2.5 dB at 60 GHz for a length of 8 mm of a back-to-back structure with the transitions at the extremities. The measured average insertion loss and return loss per transition are better than 1.36 dB and 11 dB, respectively, with a bandwidth greater than 7% at 60 GHz for a length of 1 mm (about a half of the wavelength at 60 GHz).

In this article, a novel Ka band conductor‐backed coplanar waveguide to substrate integrated waveguide transition is presented. The new structure integrates the classical current probe transition with asymmetrical stepped impedance transformer to improve the operating bandwidth. An equivalent circuit model is also given, which clearly illustrates the operational principle of this new transition. Finally, a back‐to‐back transition has been simulated and fabricated. The experimental results show that the transition has a satisfactory performance in the whole Ka band. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2731–2734, 2014
