  • 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 VSWR2 and 100% radiation bandwidth, which covers ultra wideband frequency spectrum applications. The achieved performance in the band has fairly constant5dB 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.
