Novel high gain and compact UWB antenna using multiple radiation arms loaded with rectangular patches

A novel high gain ultra-wideband (UWB) antenna is proposed. In its planar configuration, multiple radiation elements are employed in order to achieve both miniaturization and high gain. Meanwhile, a symmetric polygon is etched on the metal ground for improving the impedance matching in such a wide frequency band. The optimized geometric dimensions are obtained via full-wave simulation. A prototype of the proposed antenna is fabricated and measured results are compared with simulated results. The results show that the proposed antenna design achieves good performance as predicted.
