“…This antenna exhibits the improved reflection coefficient over the frequency range of 0.4 to 6.0 GHz. A compact UWB antenna has been designed by Tiwari et al 40 A compact sized wider bandwidth spiral shaped antenna (SSA) with two different types of feeding techniques (CPW-fed and Microstrip line) has been presented in this manuscript. Proposed SSA's exhibit stable radiation pattern, high impedance bandwidth, constant group delay, and superior gain in the frequency range (1.23 to 20GHz) and (1.68 to 20GHz) using both feed lines respectively.…”

Spiral-shaped UWB antennas, which are differ from each other in terms of feeding structure are presented in this manuscript. CPW and microstrip line feeding are used to excite the designed antenna to obtain different performance parameters. The overall physical dimensions of proposed antennas are 27 × 27 × 1.6 mm 3. These antennas are designed on low cost FR4 glass epoxy substrate with 1.6 mm thickness and dielectric constant 4.4. Impedance bandwidth (S 11 < −10 dB) obtained for measured CPW-fed antenna is 176.82% ranging (1.23-20.0 GHz) and microstrip line-fed antenna is 169% ranging (1.68-20.0 GHz). Various performance parameters of both the designed antennas are observed and calculated, such as, radiation pattern, gain, group delay, and radiation efficiency, which all are in the acceptable range for distinct UWB communication and other wireless standards. The optimized designed antennas are fabricated and tested for the validation of results and comparison among simulated and measured results of antennas have been made and found in good agreement with each other.

The paper presents a highly efficient, low cost, ultra-wideband, microstrip monopole antenna for microwave imaging and wireless communications applications. A new structure (z-shape, ultra-wideband (UWB) monopole) is designed, which consists of stepped meander lines to achieve super-wide bandwidth and high efficiency. Three steps are used to design the proposed structure for the purpose to achieve high efficiency and wide bandwidth. The antenna bandwidth is enhanced by varying the length of meander line slots, optimization of the feeding line and with the miniaturization of the ground width. The simulated and measured frequency bands are 2.7–22.5 GHz and 2.8–22.7 GHz (156% fractional bandwidth), respectively. The dimensions of the antenna are 38 mm × 35 mm × 1.57 mm, and its corresponding electrical size is 2.41 λg × 2.22 λg × 0.09 λg, where guided wavelength λg is at the center frequency (12.75 GHz). This antenna achieved a high bandwidth ratio (8.33:1). The realized gain is varying from 1.6–6.4 dBi, while that of efficiency is 70% to 93% for the whole band. Radiation patterns are measured at four operating frequencies. It has an acceptable group delay, fidelity factor, and phase variation results that satisfy the limit of ultra-wideband in the form of the time domain.

This article presents a miniaturized ultra-wideband planar monopole antenna with an oval radiator. The proposed antenna is fed by a coplanar waveguide (CPW), and two L-shaped stubs are extended from the ground plane of the CPW. This presented antenna is able to produce resonances in the lower frequency band and realize better impedance matching performance in the middle and higher frequency bands with the aid of the L-shaped stubs. The antenna was built and tested. The total size of the proposed antenna is only 26 × 20 × 1.6 mm 3 . Its measured -10 dB impedance bandwidth is 10.1 GHz (3.1-13.2 GHz). The measured far-field radiation patterns are stable in the whole operating frequency band.
