Arnfried Kemnitze current distribution of the modes, the geometry of the antenna can be modified. The aspect ratio is the important parameter in RDRA. Devising control on aspect ratio can alter resonant frequency, gain, and bandwidth. RDRA has two fold design flexibility because of two aspect ratios. The resonant m
