Executive Summary

The primary goal of this paper was to cause resonance, 1.57542 GHz, of a microstrip patch antenna reduced in length by a factor of approximately 21 to 5 mm, thus making the antenna length independent of frequency. The results obtained from the physical test, Section V, were satisfactory in that the resonant frequency of the prototype MMPA, at 1.588 GHz, is 99.71% accurate to the designed frequency of 1.57542 GHz, which strongly supports the appropriateness of symmetrical TIS as a microstrip patch antenna miniaturisation tool.
