In order to apply a normal-mode helical antenna(NMHA) to actual radio equipments, a simple impedance matching structure becomes inevitable. Authors developed a simple tap feed structure that was composed around the helical wire. However, the design equation was not clarified.
In this report, mutual inductances between the NMHA and the tap that are the most important factor of a tap feed are theoretically clarified. Next, dependences of mutual inductances to NMHA parameters are deduced basec on calculated results. Finally, a simple desien equation of the impedance step up ratio that is inversly proportional to the mutual inductances is established. |
