In this paper, a coplanar waveguide fed rectangular slot antenna tuned by a patch stub is designed and presented for ultra wideband band applications. The presented antenna exhibits a small size, a wide bandwidth of 98%, and a 6 dB average gain. Introduction In applications where size, weight, cost, performance, ease of installation, and Coplanar waveguide-fed dual exponentially tapered slot ... A uniplanar coplanar waveguide-fed dual exponentially tapered slot antenna is proposed, using a lumped-element impedance-transforming coplanar waveguide-to-slotline transition as the antenna ... TAPERED MEANDER SLOT AND COPLANAR SLOT ANTENNA FOR DUAL ... mainly by the horizontal slot width of the meander and the distance of the microstrip line termination from the slot. The other design was accomplished by the use of a coplanar patch-slot antenna (CPA) fed by a coplanar waveguide (CPW). This later design is easily tuned to operate at 2.45 and 5.75GHz, with wide bandwidth (BW). A cavity-backed coplanar waveguide slot antenna array A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz.

CPW-Fed Slot Antenna for Wideband Applications A new coplanar waveguide (CPW)-fed wideband printed slot antenna is presented, and the impedance characteristics of this antenna with different sizes of tapers are discussed. The effect of tapering angle with the resonant frequency is also observed. The fundamental parameters of the antenna such as bandwidth, return loss, gain, radiation pattern, and polarization are obtained. A Miniaturized CPW-Fed Tapered Slot Antenna in Lossy ... In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition ... slot-coupled patch antenna with coplanar waveguide feed ... finite width coplanar waveguide patch antenna with vertical fed through interconnect(272.11kb) ... a linear tapered slot antenna electromagnetically coupled with perturbed ...
