Abstract :
Although the radiation quality factor of small antennas in free space has been investigated extensively in the past, the exact effect of a conducting ground plane on the antenna bandwidth is still not clearly understood. In this paper, radiation quality factors of vertically polarized antennas above a ground plane are computed and compared with their free-space counterparts. The theoretical Q result is validated with simulation of a small spherical helix antenna.
