antennanordning comprehensive kapacitivt linked radiotorelement and it's a palm held radiokommunikationsanordning for such a antennanordning

摘要

The object of the present invention is to achieve an antenna for both receiving and transmitting circularly polarized RF signals which is smaller and lighter than prior art antennas as well as to achieve one antenna for both receiving and transmitting circularly polarized RF signals which has better characteristics for a given physical length than prior art antennas. This is achieved by providing an N-helical-filar antenna with N radiating elements coaxially arranged and defining a cylindrical envelope where each individual radiating element is capacitively coupled to another radiating element.
