“…16) is only long. Although the bandwidth is narrower compared to other reported LTSA with different feeding networks [23], [24], the proposed CPW-fed LTSA utilizing the impedance-transforming CPW-to-SL transition has the advantages of very compact size such that it can facilitate circuit layout especially in LTSA array applications. In addition, it has the merit of versatile design capability for complex impedance matching.…”

Novel impedance-transforming coplanar waveguide (CPW)-to-coplanar stripline transitions and CPW-to-slotline transitions are proposed, using planar lumped elements to realize the -section impedance-matching network in the transition structures. Simple equivalent-circuit models based on closed-form expressions are also established, from which various lumped-element impedance-transforming transitions are investigated. Examples for using the proposed transitions in the design of antenna feeding structures are also demonstrated, and successful size reduction has been achieved.

Conventional Vivaldi antenna has the advantages of ultra wideband, but its backward radiation is too large and the the gain of the main radiation direct is low [1]. On the basis of the original Vivaldi antenna, this paper designed a Vivaldi antenna element with a groove, its working frequency is from 400 MHz to 900 MHz. Grooves can change the current distribution on the antenna surface, so as to influence the gain of the antenna element, and can make the pattern more evenly. The test and simulation results show that the pattern of the modified Vivaldi antenna is more smooth than the traditional Vivaldi antenna, and the antenna gain is improved in the whole operating range.

“…In that case, it is advantageous to use a lowr substrate that can be electrically thin without resorting to a fragile, physically thin highr substrate. In at least two papers, TSAs fed by a CPW-toslotline transitions on lowr substrates have been reported [10,11] but the transition loss and resultant effect on efficiency was not characterized.…”

The power dissipation characteristics of CPW‐to‐slotline transitions are discussed. The resonant stub chosen to terminate one CPW slot in these transitions has a significant effect on the transition loss. Series‐stub designs are shown to reduce energy loss by 2.5–3 times on a low‐dielectric‐constant substrate, as compared to the more common radial‐stub design. © 2004 Wiley Periodicals, Inc.
