  • Publication number: 20020000946
    Abstract: The invention relates to an arrangement for feeding an antenna. The antenna (220) itself is symmetric. The antenna feed line (210) is also symmetric such that its conductors (211, 212) are twisted with respect to each other. In practice, half a turn is enough. The output of the stage (205) feeding the antenna is balanced. The invention facilitates a controlled radiation pattern of the antenna. The antenna feed line has a good capacitive balance, which means little interference in the operation of nearby circuits and, hence, a greater maximum transmission power. The structure is relatively simple and has low production costs.

  • Patent number: 5794159
    Abstract: A multi-mode radiotelephone (10) includes at least one antenna (12) for transmitting and receiving RF signals within at least two frequency bands. The radiotelephone also includes a first receiver (30, 34) having an input coupled to the antenna for amplifying and down-converting RF signals within a first frequency band and a second receiver (30a, 34a) having an input coupled to the antenna for amplifying and down-converting RF signals within a second frequency band. The radiotelephone further includes a first transmitter (44, 46, 48) having an output coupled to the antenna for up-converting and amplifying RF signals within the first frequency band and a second transmitter (44a, 46a, 48a) having an output coupled to the antenna for up-converting and amplifying RF signals within the second frequency band.
