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...

In recent years, wireless communications have progressed very rapidly. In order to provide with large bandwidth for any wireless application, wideband antenna design has become very important. In the reported literature [1-2], some of CPW-fed and microstrip-line-fed wide-slot antennas have been proposed for the wideband operation. The impedance bandwidths of the wide-slot designs [1-2] can reac...

A novel coplanar waveguide (CPW) fed wide tapered slot antenna (WTSA) is presented in this paper. A wideband CPW-towide slotline (WSL) transition is employed to feed the antenna. The corrugated edge structure and broken line tapered profile are also applied in this design to achieve wideband performance, as well as maintain compact size. A prototype of the antenna is fabricated. The measured re...

A CPW-fed ultra-wideband antenna was designed. The antenna was etched on a single-layer copper-cladding substrate, of which the material was FR4 with relative permittivity of 4.4, and the magnitude was 40.0 mm × 50.0 mm × 1.6 mm. The parameters of the antenna are simulated and optimized with HFSS. This paper proposes a new trapezoidal CPW-fed UWB antenna that the bandwidth (return loss ≤ −10 dB...

In this paper, a broadband rectangular microstrip patch antenna fed by coplanar waveguide feed with two slots in the ground plane is proposed. Investigations are carried out using coplanar waveguide feed with slotting in the ground plane to optimize the broadband operation. A sensitivity analysis shows the variation of return loss with different antenna parameters. This design of broadband ante...

In this paper, a design of compact coplanar waveguide fed UWB slot antenna is presented. The proposed antenna has simple structure consisting rectangular slot with uneven coplanar ground structures. The proposed antenna structure is investigated by using MoM based electromagnetic solver IE3D. The simulation and measured results show that the antenna offers performance for wideband system from 4...
