Abstract
In this paper broadband and compact power divider is presented. The proposed circuit made up of two micro strip transmission lines. A pair of low and high impedance lines for equal and unequal power-dividing ratios. The proposed power divider exhibits arbitrary and non-arbitrary power divided ratios. Design equations for proposed circuit power division ratio cases are given. For the equal ratio case, two symmetric coupled Micro strip lines required. The unequal ratio case, two asymmetric coupled Micro strip lines required. Proposed power dividers has been study and investigated. The proposed Hybrid power divider operating at 2.4 GHz with power dividing ratio of 1:2 and 1:4 are designed, fabricated, measured respectively. The measured results are in good agreement with the simulated results. The power divider has been designed on FR4 dielectric substrate with relative permittivity εr=4.4 and thickness 1.6mm. The designed power divider miniaturized by using the T-shaped feed techniques. The overall size of the power divider is 42mm * 86mm*1.6mm3. The results shows that the isolation between output ports is found to be better than –15 dB and return loss at each port is less than -10dB.
