摘要：

A novel ultrawideband low-profile high-efficiency indoor antenna formed by the printed slotted patches with lumped elements loading technique is presented. By loading the parallel and series resistors, the surface current of the proposed antenna is distributed in a traveling wave, thereby effectively widening the impedance bandwidth of the antenna. By loading the inductor, the radiation efficiency of the antenna is improved while maintaining the compact size. The proposed antenna can cover 0.1 G-3 GHz ultrawideband width and has high efficiency in the whole frequency band. Moreover, the proposed antenna has a low-profile compact size of 310 x 270 x 0.8 mm(3). Good omnidirectional radiation characteristics are achieved over the entire frequency range. Details of the antenna design and experimental results are presented and discussed.
