Abstract
A rectangular disk monopole antenna with a novel notched ground for potential low-cost ultra-wideband applications is proposed. This notched ground can adjust the electromagnetic coupling effects between the disk monopole and the ground plane, and improves its impedance bandwidth dramatically without any cost of size or expense. Its impedance bandwidth defined by VSWR <2 is from 3.1 to 11.8GHz with a ratio of about 3.8:1. Furthermore, this novel monopole antenna exhibits a nearly omnidirectional radiation pattern with compact size and simple structural configuration, which is suitable for various wideband applications.
