Abstract A novel compact UWB magnetic antenna is designed and manufactured. This antenna has a balanced feed , moreover, numeric simulations and experiments are carried out to investigate its return loss, radiation behavior, and time-domain response. The antenna offers 107% impedance bandwidth under VSWR<2 and 100% radiation bandwidth, which covers ultra wideband frequency spectrum applications. The achieved performance in the band has fairly constant>5dB gain, and suitability for pulse transmission with minimized distortions. Further more, it have relatively large magnetic near-fields that are difficult to undesired coupling with near-by objects, so it is very suitable for application to some environment cluttered up with objects such as home. It makes some sense to the application.
