| Abstract: | In the present paper, the improvement of the return loss of a power
splitter/ divider, designed by partial removal of electromagnetic band gap (EBG)
rods, has been investigated. The EBG used is a rod structure and shows a band
gap in
the range 2.2395 - 2.5774 GHz. The power splitter has a return loss of 2.45 GHz
which falls in the range of the band gap.
It has been found that a larger matrix of the EBG structure is needed in order
to improve the return loss significantly. However, the removal of rods, as the
matrix size is increased, needs to be done with a fixed ratio of the input feed
length to coupling length in order to maintain the same resonant frequency. The
improvement in the return loss has been significant from -19.932 dB (for a 5×5
matrix) to -37.214 dB (for a 17×17 matrix). |
