A printed extremely wideband antenna for multi-band wireless systems

In this paper, a printed elliptical monopole antenna, which is fed by a modified, tapered microstrip feed is presented. The measurements indicate it has an extremely wide impedance bandwidth of 1.08-27.4 GHz. The antenna can support many communication and wireless other services, such as GPS, GSM1800, WLAN, UWB communication systems (3.1-10.6 GHz) and part of the UWB vehicle radar systems (22-29GHz). It is also suitable for extremely wideband spectrum monitoring, interference characterisation and similar EMC/EMI applications, as well as extremely broadband RF energy scavenging. The proposed antenna design and results are discussed.
