Özet

In this article, simple but efficient expressions for determining the dual-frequencies of equilateral triangular compact microstrip antennas (ETCMA) with a shorting-pin are presented. Two expressions related to offset factor functions were derived with the use of a differential evolution optimization algorithm. The dual-frequencies of an ETCMA with a shorting-pin were then calculated by multiplying the offset factor functions with the single resonant frequency formulation of a conventional equilateral triangular microstrip antenna. The proposed approach was demonstrated through successful comparison with simulated and measured data. (c) 2013 Wiley Periodicals, Inc.
