t SLOT ANTENNA FED BY A CPW LINE WITH TAPERED TRANSITION ABSTRACT: A tapered coplanar waveguide (CPW) transition is pro-posed in order to facilitate the connection between a slot antenna and coaxial connector. The broadband bow-tie slot antenna is considered as an example in this design. The tapered transition is utilized to optimize the connection of two 50 CPW lines with different widths. A narrow 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. Nonplanar Linearly Tapered Slot Antenna With Balanced ...
A design approach for the compact broadband coplanar waveguide (CPW)-fed tapered monopole antenna (TMA) for C-band applications is presented, in this paper. The proposed antenna is composed of a CPW-fed monopole antenna with tapered structures, embedded with symmetric open-ended L-slots, and a tapered shape is cut from the top sides of the CPW-fed ground plane.

T.G.Ma.et.al presented a new coplanar waveguide- fed tapered ring slot antenna for ultra wideband (UWB) applications[22]. This antenna consists of a 50 coplanar waveguide feeding line, wideband coplanar waveguide-to-slot line transition, and a pair of curved radiating slots. The impedance bandwidth is from 3.1 GHz to more than 12 GHz. Dual Port Ultra Wideband Antennas for Cognitive Radio and ... elements of this antenna are, i. A coplanar wave guide (CPW) to coplanar strip line (CPS) transition (Figure 1a) ii. Tapered slot antenna with elliptical tapering (Figure 1b) and iii. A rectangular loop slot antenna (Figure 1c). In this design each of these antenna elements were effectively integrated to form a dual port High Gain Planar Antenna Structures for Ka-band Applications High Gain Planar Antenna Structures for Ka-band Applications Kiran Phalak Antennas are an essential part of a communication system as they control a coverage area of the signal. The millimeter wave band has the potential to offer numerous radio applications which require the large bandwidth channels.

Linearly Tapered Slot Antenna Impedance Characteristics
A one-element bow-tie slot antenna fed by a 50 Ω coplanar waveguide is designed for the X-band operation. The measurements of this antenna show two operating bands centered at 8.3 and 11.7 GHz with bandwidths 18% and 17.4%, respectively. An array combination of two of these antennas fed by one CPW achieved 50% bandwidth from 8.7 to 14.5 GHz.
