Abstract:
In this paper, an ultra-wideband (UWB) monopole printed antenna with wing-shaped coplanar waveguides (CPW) feeder is proposed, in which the wing-shaped CPW feeder is used to increase the impedance bandwidth. A CPW-fed antenna is used in this design for its simple structure, compact size and ease of integration with microwave circuits. The proposed antenna is fabricated on Durion Roger R4003c, 22×41 mm² substrate and measured. The simulated and measured results show that the antenna operates between 2.04 to 11.67 GHz. The unique wing-shaped CPW feeding structure causes a significant increase on the bandwidth of the proposed antenna compared to the present patch antennas. Also it removes unwanted ripples from the return loss and improves antenna's pattern.
