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

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.
