Abstract A Co-Planar Waveguide fed circular ultra-wide band antenna with modified ground-plane and feedline is designed on a FR4 (ϵr=4.3) substrate of thickness 0.01λ0. The proposed antenna exhibits an overall impedance bandwidth ranging from 2.99 GHz to 18.0 GHz and beyond (with S11< -10 dB). Design parameters have been optimized to achieve the UWB bandwidth. The measured radiation patterns of this antenna are omnidirectional in H- plane and bidirectional in E-plane. An extended impedance bandwidth is achieved as a result of modified feed-line. The proposed antenna can be used for medical imaging and urban IoT applications.

In this proposition, a traditional UWB antenna with twofold indent channels was intended for a few remote applications. The exhibited antenna is outlined having estimations of 30 × 35 × 1.6 mm3 with a fix of rectangular staircase design. The dismissal bands are WLAN at 5 GHz (5.1 - 5.8 GHz) and the satellite X-band from space to earth (7.25 - 7.75 GHz). The patch with a step design with a modified π-formed opening gets the ultra-wide band. The UWB scope of 3.1 - 10.6 GHz affirmed by FCC can possibly cause interferences in the various wireless systems applications.. With a specific end goal to lessen these interferences, we settled on the band indent. In this proposed outline, the WLAN has scores setting a U-molded opening in the patch and the X-band has indents with a reversed T-shape in the ground plane.

This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna to achieve UWB and Single/Dual continuously tunable-notch behaviors. The Single/Dual notched was continuously tuned to our desired frequency band by changing the value of the capacitors. The antenna designed and fabricated to validate these behaviors had a compact size of 24 × 30.5 mm2, including the ground plane. The radiation patterns were very clean due to the placement of the proposed resonator in the special ground plane. Moreover, the presented novel resonator and switching technique was compared with the recently proposed resonators and their switching techniques. The prototype for the antenna was also developed in order to validate its performance in wireless vital signs monitoring. The presented miniaturized resonator based antenna was utilized for tumor sensing and simulations were provided in this regard. Moreover, the deployment of the proposed resonator based UWB antenna sensor in Pipeline Integrity Monitoring system was also investigated and discussed.
