Abstract :
An antenna system comprising of colocated and copolarized magnetic dipole (loop) and electric dipoles has been implemented in a planar stacked configuration. All the three elements of the antenna system show good return loss and coupling between copolarized elements is observed to be less than -10 dB. The feasibility of employing such a system to realize more information channels in the same frequency band has been demonstrated. It is expected that future work on the design aspect of the antenna elements will lead to improvement in the coupling performance of the copolarized elements. Also, means of implementing another orthogonal loop will be explored with the eventual aim of realizing the six element structure using printed loops and dipoles.
