K-BAND WILKINSON POWER DIVIDER BASED ON A TAPER EQUATION

In this paper, a microstrip circuit structure for a K-Band Wilkinson power divider is presented. The designed power divider is composed of two-step taper stubs based on empirical equations. The symmetry of this circuit allows a half circuit analysis through looking at the odd- and even-model excitations. To demonstrate its performance, the proposed Wilkinson power divider has been fabricated and tested. Results show that the measured insertion loss is less than 0.3dB and that the output re∞ection, input re∞ection and isolation are better than 16dB, 22dB, 16dB, respectively, in the frequency range from 18GHz to 27GHz.
