This study presents the resonant frequencies of several antennas, which are dual-frequency antennas. These antennas possess two shorting pins to form dual frequency. Among several methods to provide dual operation, two shorting pins are used to form dual frequency equilateral triangular antennas since there are limited studies on this issue and higher frequency ratios are achievable. The present study has been done with this in mind in order to contribute to related literature on such antennas. Here, the parameters that affect the resonant frequencies of the antenna are also evaluated. The thickness, side length, and shorting pin positions are changed numerous times, and the resonant frequencies are examined according to the change of these parameters. Finally, the frequency ratios are determined for each variation, and the results are compared. The proposed antennas in present study achieved a frequency ratio around 5.7, which is significantly higher from the ones presented in the literature.
