antenna have been widely studied for broadband operation, especially with coplanar waveguide (CPW) feed lines [5]-[6], but they are quite complicated to design for optimal antennas. Recently, the study of a bow-tie slot antenna with CPW-fed has been presented [7]. This antenna has a geometry structure IET Digital Library: CPW-fed bow-tie slot antenna for ultra ... A modified coplanar waveguide (CPW)-fed bow-tie slot antenna is proposed to have a wider impedance bandwidth than that of the conventional CPW-fed bow-tie slot antenna. The antenna structure remains simple and has better impedance matching for ultra-wideband communications obtained through the adjustment of bow-tie flare angle and stem width. Design of Dual-Band Bow -Tie Slot Antenna By Using HFSS significant variation and studied the influence of slot width and the extended angle on the CPW-fed bow-tie slot antenna. By changing the slot width, a 36% bandwidth and gain of 5.59dbi ) was obtained when the extended angle was 200[2]. Studied the performance of the CPW-fed bow -tie slot antenna with different flare angles of the bow-tie slot.

In this paper, a modified slot bow-tie antenna fed by a coplanar waveguide (CPW) is investigated for wideband operation. It is designed to work on a thin substrate (h = 0.787 mm) with a low dielectric constant (epsivr = 2.2) operating at two frequencies (1.8 and 2.4 GHz).
Paper Title (use style: paper title) To avoid the "staircase" approximation, the bow tie's surface is modelled by planar triangular patches and the method of moments is afterwards applied to solve the EFIE using the well- known Rao-Wilton-Glisson (RWG) basis function [27] and … Microsoft Word - str_0693-0699

line. Bow-tie and bow-tie slot antennas are planar-type variations of the biconical antenna that has wideband characteristics as in [5] and [10]. A number of bow-tie slot designs are introduced, which demonstrate wide BW that range from 17% to 40%. The WIFI frequency is divided into two bands: 2400-2484 MHz and 5150-5850 MHz;
Abstract: 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. A modified bow-tie slot antenna fed by a CPW-to-CPW ... Abstract: A novel CPW-fed asymmetric bow-tie slot antenna for UWB applications is examined. The antenna has been successfully implemented, exhibiting 7.94 GHz of impedance bandwidth. By incorporating inductively coupled bow-tie slots at both sides of the CPW line, evident enhancement of the impedance behavior is demonstrated.
