| Abstract(in English) | This paper proposes a new configuration of lower pitch angle helix (LPH) with conical taper-end to decrease the height of helix and derivation of its axial ratio bandwidth. In general, lower pitch angle helix is not suitable for axial mode operation so that good performance cannot be obtained. Drastic improvement can be achieved by introducing conical taper-end for LPH to improve axial mode operation. Further, a new indication of axial ratio bandwidth and height of helix can be derived that optimum solution of those can be revealed. As a result, height of LPH can be achieved as about half of that against normal pitch angle helix with broad bandwidth. A LPH has been designed and manufactured in the L-band for application of satellite communication and its effectiveness has been confirmed through design and test results. |
