Summary:

This paper proposes a feeding structure for Annular Ring Patch Antennas (ARPAs) with TM11 and TM21 modes antenna on a substrate. In this feeding structure, each ARPA is fed by coupling from the top for ease of fabrication and adjustment. There are different points about the influence for bandwidth that feeding size and arc-shaped line among TM11 and TM21. In this paper, the influence of the coupling line size and feeding position on the bandwidth is discussed.
