## Resonant Frequency Formula . The resonant frequency is the frequency of a resonant circuit.A Resonant circuit is also identified as LC circuit or tank circuit.This circuit comprises of inductor and capacitor attached parallel to each other.

Design of Modified Bowtie Antenna for Wireless Applications ... An empirical formula of resonant frequency of bow- tie antennas is presented, which is based on the cavity model of microstrip patch antennas as in . A procedure to design a bow-tic antenna using generic algorithm (GA) in whichthe formula is taken as a fitness function is also given. An optimized bow-tic antenna by genetic algorithm is measured.
