Waveguide slot antennas are often used as omnidirectional microwave antennas.The waveguide slot antennas we will be discussing have longitudinal slots in the broad face of stan-dard rectangular waveguide, paralleldimension. Later, we shall see that a tapered aperture illumination can increase.
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. COPLANAR WAVEGUIDE FED MULTI-SLOT ANTENNA ABSTRACT: A bow-tie slot antenna with tapered connection to a 50Ω coplanar waveguide (CPW) feed line is introduced and its dimensional parameters have been studied for wideband operations in the X-band. A set of two element bow-tie slot antennas fed by one CPW is also introduced for wider bandwidth and improved gain. A W-Band Linear Tapered Slot Antenna on Rectangular ... Abstract: A W-band (75-110 GHz) coplanar-waveguide (CPW)-fed linear tapered slot antenna (LTSA) on rectangular-grooved silicon substrate is presented. Compared to its ungrooved version, the W-band CPW-fed LTSA shows significantly improved endfire radiation patterns in the whole band. Design of Compact Coplanar Waveguide Fed Slot Antenna for ... Antenna dimensions: a=0.3, b=2.5, z=0.03mm Where, All dimensions are in mm Shaded area denotes metal Remaining area denotes slot Inductive fed Coplanar Waveguide slot antenna structure is shown in figure 3.

attached to the antenna and is realized in differential technology (coplanar strips for instance), or if the transition to single-ended technology has been realized within the LNA. Study and Design of a Differentially Fed Tapered Slot Antenna Array Eloy de Lera Acedo, Student, IEEE, Enrique Garcia, Vicente González-Posadas, José Luis Vázquez-
A radiating tapered notch antenna (sometimes known as a Vivaldi antenna) is fed by a section of slotline, which in, turn is fed by a coplanar waveguide. The transition from the unbalanced coplanar waveguide to the balanced slotline is accomplished by an infinite balun, where the center conductor of the coplanar waveguide terminates on the slotline conductor opposite the ground conductor of the ...
