Abstract
A novel monopole antenna with two parasitic elements added is presented for broadband applications. The impedance and radiation characteristics of the antenna are investigated experimentally and numerically. For the proposed antenna, a bandwidth of 97.1% with |S~11~| < β10 dB is achieved, and omnidirectional radiation pattern is obtained. The results are very attractive for mobileβcommunication systems.
