Abstract :
An electrically small and low profile triple-band split ring antenna is presented. The antenna itself operates at three frequency bands of 430MHz, 680MHz and 990MHz. It is 100mm long which corresponds to λ/7 at the lowest working frequency of 430MHz. The antenna is placed over a small artificial magnetic conductor which works at 430MHz to form a very compact, conformal platform tolerant antenna. Significant bandwidth and gain improvements are achieved for the combined structure when compared to the performance of the antenna alone.
