In this study, a new compact coplanar waveguide-fed wideband circularly polarised slot antenna is designed and fabricated. To achieve circular polarisation, the slot in the ground plane is truncated at one corner and excited by a modified L-shaped radiating element. To achieve wide axial ratio bandwidth (ARBW), one end of the L-shaped patch is connected with the ground via a slit. The ARBW is further...
In this paper, a CPW-fed dual band antenna for Circular Polarization (CP) is proposed and fabricated. CP is achieved using an 'L' shaped radiating patch and a one corner truncated slot in the ground plane. Dual band CP is achieved by connecting one end of the 'L' shaped patch to the ground plane and adding a stub to the ground plane. The proposed antenna has impedance bandwidths (S11 <-10 dB) of...
A CPW excited rectangular slot antenna for circular polarization is presented. The feed line is terminated on a circular disc having a slant rectangular slit. Inverted L-shape strips are attached to the ground plane and protrude into the rectangular slot. The measured impedance bandwidth achieved by the antenna is 124 % from 2.4 GHz to 10.2 GHz The measured bandwidth of circular polarization with...
A circularly polarized slot antenna for bluetooth applications is proposed in this paper. The rectangular slot is excited by a coplanar waveguide feed terminated on a hexagonal patch. The measured impedance bandwidth is from 1.6 GHz to 3.0 GHz while the measured axial ratio is from 2.00 GHz to 2.65 GHz. The antenna has a peak gain around 3–4 dBi in the operating band. The radiation patterns are omnidirectional...
This paper presents CPW -fed Square Shaped fractal antenna. The Antenna has been designed on FR4 substrate ??r = 4.3 and thickness 1.53 mm. The antenna has been fabricated and tested using VNA. The experimental result exibihits dual bands i.e. from frequency 0.79 GHz - 2.24 GHz and from frequency 3.53 GHz to 12.29 GHz. This corresponds to 1.45 GHz and 8.76 GHz respectively. The lower end frequency...
