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. The configuration of one CPW feeding two elements of this antenna is simulated and it ac...
For the purpose of wideband operations, a bow-tie slot antenna fed by a coplanar waveguide (CPW) is investigated. The design was realized using a tapered metal stub introduced in the middle of the bow-tie slot. The modified structure shows wider bandwidth over the conventional bow-tie slot antenna. Parametric study of this new antenna results in a design procedure that helps design this class o...
planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Lowcost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate. This structure is designed with Finite Element Method (FEM) using...
The intent of this paper is to compare two designs of RFID antenna which is used for Ultra High frequency (UHF) and Ultra wideband (UWB) applications. Here the comparison of Hybrid design and XETS design is done. In hybrid design the antenna simultaneously operate on both the bands viz.UHF as well as UWB. In XETS design antenna operates only for UWB. Hybrid antenna is planar antenna. There is a...
The characteristics of a bow-tie slot antenna with tapered tuning stubs fed by a coplanar waveguide (CPW) are investigated. The effects of the antenna dimensional parameters are studied through simulation results and design procedure is developed and verified for different frequency bands. The antenna shows wideband characteristics for radar and wireless communication applications. Numerical si...
A method is presented which is aimed at increasing bandwidth of the tapered slot antenna by just finding the optimum tapering profile of the antenna without the need to increase its size rather than decrease. In this paper, an ultra-wideband (UWB) antenna with a compact size of 16 mm x 20 mm is proposed for USB dongle applications. Theproposed antenna has been designed on FR4 substrate dielectr...
An Ultrawideband (UWB) high gain compact Vivaldi antenna with end fire radiation patterns is presented for radar and microwave imaging applications. The antenna is operating for 2.9GHz to more than 11GHz with -10dB impedance bandwidth and is designed on low cost FR4 substrate of thickness 0.8mm. While designing the proposed antenna, initially a compact exponential tapered slot Vivaldi antenna i...
This paper presents an antipodal linearly tapered slot antenna (ALTSA) array with the newly emerging substrate-integrated coaxial line (SICL) technology. Each element of proposed consists two vertically stacked antennas (TSA) inner conductor a SICL as shared fin. The vertical symmetry this radiating structure significantly suppresses cross-polarization level. By employing SICL-based power split...
A compact wide-slot antenna with microstrip-fed monopole for ultrawideband (UWB) application. The monopole is composed of an elliptic patch connected to a trapezoid one. The radiator patch is attached to a 50microstrip feed line by a smoothly tapered line to enhance the wideband matching. A hexagonal slot is etched from a finite ground plane placed on the other side of the substrate. The antenn...
