“…According to the principle of the microstrip-to-slotline transition, an alternative microstrip-to-CPW transition was recently developed using two pairs of open-circuited microstrip and short-circuited slotline stubs with radial shape [4]. Moreover, a few transition structures were presented in [7]- [9] to realize the wave transmission between the microstrip and CPW with a finite ground width.…”

Abstract-An improved broad-band microstrip-to-coplanarwaveguide (CPW) transition is developed on a basis of the frequency-dependence characteristic of an electromagnetic surface-to-surface coupling. A self-calibrated method of moments is extended to model this unbounded two-port discontinuity with the two dissimilar microstrip/CPW feeding lines. Numerical results are provided to demonstrate its frequency response of transmission under varied strip/slot dimensions and further exhibit its attractive ultra-broad-band transmission with low radiation loss.

“…Since the antenna elements of the array consist of microstrip patches, and the corporate feed of microstrip line both with ground on the backside of the substrate, transitions are required. Several designs of microstrip to CPW transitions are reported in the literature [20][21][22]. It is also possible to design a transition when the signal traces of CPW and microstrip are continuous on one side of the substrate whereas electromagnetic coupling is used between the overlapped ground traces of CPW and microstrip which are on either side of this substrate [22].…”

Abstract-This paper presents the design, development and experimental characterization of a monolithic phased array antenna integrated on a microwave laminate.A four-element linear antenna array is realized by cofabricating the corporate feed network, microstrip-CPW transitions, DC blocks, and mesoscale phase shifters on the same substrate. The phase shifters used here are electrostatically actuated and their operation is similar to that of the distributed MEMS transmission line phase shifters. Various components of the array are designed and are individually evaluated before fabricating together. The measured radiation pattern characteristics for this array shows a scan angle of 10 • in the Xband. All fabrication processes employed here can be performed at a good printed circuit manufacturing facility. This simple approach of cofabricating various components can be readily extended for large phased arrays required in radar and space communication applications.

“…With this thickness, coplanar-microstrip transitions are generally "easier" to realize, in terms of etching, that those on thin films. We essentially focus our attention on the transitions proposed by Strauss (Straub, et al, 1996) and Zhu (Zhu & Melde, 2006). The structures 1 and 2, shown in figure 8, have the advantage of a homogeneous lower ground plane.…”
