摘要：
A new compact dual-linearly polarized ultrawide-band (UWB) antenna for VHF/UHF applications is proposed on this letter. The antenna is miniaturized thanks to inductive loading and lumped resistances. In addition, to reduce back-radiation and to optimize the impedance matching at low frequencies, a ferrite layer is placed close to the radiating element. This antenna provides broadband characteristics and unidirectional radiation patterns over the whole bandwidth with a length and a height respectively limited to lambda(LF/6) and lambda(LF/13), where lambda(LF) is the wavelength at the lowest frequency of the operating band. Simulations and measurements are found to be in good agreements.
