Abstract
Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band. If an antenna is resonant, it will be matched to the transmission line and/or transmitter and the bulk of the signal will actually be transmitted, not reflected back and wasted as heat (i.e. Standing Wave Ratio SWR). This paper analyzed the S-parameter variation with the frequency and noted its value at the resonant frequency of 1.399GHz in which the value was very low and hence it indicates that there was purely matching at this frequency were most of the signal was transmitted and no reflection was observed.
