A new, very simple expression for the effective side length is presented for the resonant frequency of the equilateral triangular microstrip patch antenna. It is obtained by using a modified genetic algorithm, and useful to antenna engineers for accurately predicting the resonant frequencies of the equilateral triangular microstrip antennas. The theoretical resonant frequency results obtained by using this new effective side length expression are in very good agreement with the experimental results available in the literature.
