Design of Ultra-wideband Monopole Antenna with Band-notched and GPS Circular Polarization Characteristics
In this paper, a printed disk monopole antenna with coplanar waveguide (CPW) feeder for ultra-wideband (UWB) system and global positioning system (GPS) application is proposed. The antenna is implemented with the conventional radiating disk element that would have benefit on manufacturing process and thus being cost-effective 5, 6. In addition, it utilizes annular stub to reduce current distribution of the right-hand side radiating element to achieve the circular polarization (CP) 2 for GPS application around 1.575 GHz. The impedance bandwidth of the proposed antenna can range from 3 GHz to 11 GHz for VSWR< 2 with the band rejection characteristic in the frequency band from 4.8 GHz to 6 GHz. Since the antenna presents a notched band from 4.8 to 6 GHz, it can prevent the RF interference from the wireless local area network (WLAN) 802.11a 1. This proposed antenna shows a monopole-like radiation pattern with good agreement being obtained between the simulation and experiment results.
