The arms and the total length of the F determine the resonance frequency of the antenna. The inverted F shaped antennas are used in the cell phones. The outcome showed that the middle length of the antenna determines the input match and gain of the antenna. We achieved the highest gain of 6.32 dBi at 4.21 GHz frequency with input match of -16.91 dB.enginfo:eu-repo/semantics/restrictedAccessConference paper00040897780003810.23919/ROPACES.2017.7916043F-shapedAntennaRadiationMonopolePatch antenna2-s2.0-85020063551
