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 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.

This paper considers a linear tapered slot antenna element with electromagnetically coupled feed and discusses the matching and the radiation characteristics. In the proposed antenna element, the coplanar line with perturbed feeder, that is, the coplanar waveguide, is considered as a coupled slot line.
