Microstrip line(s) as new feed for exciting a cylindrical DRA with higher order HEM12δ mode

Different feed techniques are used in dielectric resonator antenna (DRA). Very recently, one higher order mode (HEM
_12δ
) has been successfully excited using some unconventional techniques. Yet another new technique is proposed in this paper, which is absolutely planar in configuration. Two different feed geometries have been explored indicating potential scope of applications.
