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

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.

Beam-scanning SIW antennas based on association of various shaped slots | IEEE Conference Publication | IEEE Xplore
This paper presents a new switched beam antenna array working at 26GHz for future 5G application, based on the sub-arrays containing an association of various shaped slot (L, U, S) engraved in Substrate Integrated Waveguide (SIW). The phase shift between each slot is obtained by adjusting the position of transversal slots. The beam tilt is obtained by choosing the adequate slots combination. Finally SPDT switches can be used to control the antenna beam in 8 different directions between -46° and 46° in the same plane or to combine different sub-arrays to carry out multi-beams antenna array. Results of simulations (CST Microwave) are given and validate the proposed solution.
