Double Exponentially Tapered Slot Antenna (DETSA) on Liquid ... In this paper, a double exponentially tapered slot antenna (DETSA) on LCP organic material suitable for packaging and integration with other components is introduced and proposed for the UWB range with gain above 7 dBi and return loss below -10 dB for the whole frequency range. The DETSA is a variation of the Vivaldi antenna, with the outer Vivaldi Antenna Vivaldi antennas are simple planar antennas that are very broadband. The polarization is linear, and the basic antenna structure is shown in Figure 1: Figure 1. Basic Geometry of a Vivaldi Antenna. In Figure 1, we have the antenna feed connecting two symmetric sides of a planar metallic antenna. To the left of the feed is is a short-circuit.

A Ka-band Planar Printed Antipodal Linearly-tapered Slot… The broadband and high gain nature of tapered slot antennas (TSA) have been reported for years. Due to its coplanar structure, the TSA is easily integrated with MICs.applied in TSAs, including coplanar waveguide (CPW)-to-slot transition, coaxial-to- slot transition, or even finline feeds, all face... 8.5 waveguide-fed slot antennas
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 Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. V-Band Linear Tapered Slot Antenna Array Using Glass-Based ... IPD technology, compact V-band antenna arrays can now be realized on-chip. In this work, a coplanar waveguide (CPW)-feed V-band 4×1 linear tapered slot antenna (LTSA) array is demonstrated using a glass-based IPD technology. To reduce the size of the antenna feeding network, the compact lumped-element CPW-to-slotline transition in [4] is adopted.
