    摘要: An antenna arrangement is disclosed for personal radio transceivers in which a main antenna (1) extends out from the housing (3) of the transceiver excited by the high frequency connector thereof and an auxiliary antenna (4) is coupled to the cold terminal of the connector to form a counterweight to the main antenna (1). Both the main and auxiliary antennas (1, 4) are resonant and shorter than the quarterwave-length, whereby the housing (3) gets to a potential minimum and the effects of the close presence of the human body on the radiational properties will be reduced.

    摘要: A ground-plane antenna comprises a quaterwave resonant radiating rod (1) made of a hollow tube in which a central earthing rod (7) is arranged to form with the internal cylindrical wall of the radiating rod a line section short-circuited at the upper end. A further line section (16) open at the lower end is arranged in the extension of the short-circuited line section to form a combined tapped line section therewith having an electrical length substantially equal to the quarterwavelength, in which the combined line section is coupled with its tapping points in parallel to the input terminals (4, 5) of the antenna, whereby the susceptance represented by the combined line section is capable of compensating the changes of the antenna reactance within a fairly wide band.
