Abstract :
A novel printed antenna configuration in the form of a chakra (wheel) is presented. The antenna has design parameters such as axle radius, rim radius, and shaft location. The antenna exhibits multiple resonant frequencies with dominant mode radiation patterns. The lowest resonant frequency is five times smaller than that of a regular circular microstrip patch antenna of the same physical size.
