Abstract
A portable radio communication device, comprising: a housing (78); antenna means for transmitting and receiving RF signals; transmitting and receiving circuits arranged in the housing; at least a conductive portion; antenna feeding means; and, a user interface. The antenna means includes a transmitting antenna (60, 61), and a receiving antenna (60, 61, 65, 78). The transmitting antenna, and the receiving antenna have orthogonal radiating characteristics in relation to each other. The transmitting and the receiving antennas can be of an electric dipole type or a magnetic dipole type. An antenna system including a transmitting and a receiving antenna is also disclosed.
