Wideband Uni-Directional CPW-fed Slot Antennas Using Loading Metallic Strips and a Widened Tuning Stub on Modified-Shape Reflectors

Spiral Tuning Stub CPW-Fed UWB Slot Offset, Edge Cleft and Edge Slotted Antennas

After the release of the unlicensed Ultra Wideband (UWB) spectrum 3.1 GHz to 10.6 GHz for the commercial purposes by the Federal Communications Commission (FCC), industries and academia pay much attention due to its properties of excellent immunity to multi-path interference, high secured data rate, low power consumption, and simple configuration. The feasible UWB antenna design face some chall...

Multiband CPW-Fed Slot Antenna with L-slot Bowtie Tuning Stub

This paper presents a multiband CPW-fed slot antenna with L-slot bowtie tuning stub. The proposed antenna has been designed for PCS 1900, UMTS, WLAN 802.11 a/b/g and bluetooth applications, with a cost-effective FR4 substrate. The proposed antenna still radiate as omni-directional in azimuth plane and sufficient bandwidth for all above mentions. The proposed antenna works as dual-wideband, band...

Design of CPW-Fed Dual-Band Printed Monopole Antennas for LTE/WiMAX/WLAN and UWB Applications

In this paper, two miniaturized (20 × 20mm2) coplanar waveguide fed slot antennas are proposed. Both the antennas are characterized by ultra wide impedance bandwidth while one of them has an additional narrow band near 2.5GHz. The radiating element of the proposed antennas is a modified rectangular geometry which is excited by a 50 ohm line. The slot in the ground plane is stair case shape for ...

Analysis of Different Shapes of Radiating Patch and Ground Plane in Wideband CPW - Fed MSA

Various Coplanar Waveguide fed microstrip antennas with different ground planes and different radiating patches for broader bandwidth are proposed. The effect of changing periphery of the radiating patch from square to pentagon, pentagon to hexagon, hexagon to octagon and octagon to circle on resonance curve is studied. Similar study has been done by changing the shape of ground plane. The conf...
