Circular Slot loaded ultrawideband circularly polarized Antenna | IEEE Conference Publication | IEEE Xplore
In this paper, a circular slot loaded circular monopole antenna for ultrawideband circularly polarized applications is presented. The antenna consists of a circular radiator fed by a modified feedline and multiple slots loaded modified coplanar waveguide (CPW) ground plane. The ground plane is also loaded with quarter elliptical slot and semicircular stub to achieve circular polarization. The overall dimensions of the proposed antenna are 17×20 mm2. The antenna has an impedance bandwidth of 4.41-14.0 GHz (104.2%) and axial ratio bandwidth (ARBW) of 5.87-13.66 GHz (79.77%). It has a peak gain of 5.34 dBi. The proposed antenna provides right hand circularly polarized (RHCP) radiation patterns along +z axis. It has advantages of compact dimensions, wide impedance bandwidth and wide axial ratio bandwidth over previously reported structures.

Design of CPW-fed asymmetric slot UWB antenna for wireless application | Journal of Electronics (China)
A compact Ultra-WideBand (UWB) slot antenna is presented in this paper. The slot is modified rectangular in shape and asymmetrically cut in the ground plane. A hexagonal patch with two stepped CoPlanar Waveguide (CPW) feed is used to excite the slot. Wider impedance bandwidth is achieved due to the extra inductive reactance created by the asymmetric slot which neutralizes the capacitive reactance of the hexagonal patch. The measured impedance bandwidth of the proposed antenna is 11.85 GHz (2.9–14.75 GHz). The radiation patterns of the proposed antenna are obtained and found to be omni-directional in H-plane and bi-directional in E-plane.
Comparative Study, Design and Performance Analysis of Wide Slot Antenna with Patch-Feed for Bandwidth Enhancement | PDF
This document presents the design and simulation of a triangular wide slot antenna with a triangular patch feed. The antenna achieves an impedance bandwidth of 116% from 2.1 GHz to 7.9 GHz. Various parameters of the antenna design were analyzed through simulation to understand their impact on bandwidth, including patch length and width, feed gap width, and waveguide width. Sensitivity analysis showed that a patch length and width of 15 mm, feed gap of 2.5 mm, and waveguide width of 0.7 mm produced an optimized performance with stable radiation patterns across the operating band. The antenna demonstrates potential for applications requiring wide bandwidth such as WLAN, Wi-Fi, and WiMAX. - Download as a PDF or view online for free

Cpw fed uwb antenna with wi max band-notched characteristics | PDF
1) The document describes a coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with a band-notch feature to reject the WiMAX band (3.35-3.8 GHz).
2) The antenna consists of a circular disc truncated at the top with a folded U-slot etched near the edge to produce the band-rejection characteristics.
3) Measurements show the antenna operates from 3.1-12 GHz with rejection of the WiMAX band, and it maintains an omnidirectional radiation pattern and stable gain across the UWB band except at the rejected frequencies. - Download as a PDF or view online for free
