METHOD FOR CONTROLLING DIRECTIVITY PATTERN OF ANTENNA FACILITIES, SET OF ANTENNAS, AND RADIO COMMUNICATION DEVICE Russian patent published in 2005 - IPC

FIELD: transmission and reception of circular-polarization radio-frequency signals; radio communication devices.

SUBSTANCE: proposed method for controlling directivity pattern of antenna facilities used to receive circular-polarization signals and suited for use with portable terminal that incorporate N spirally configured radiators (12₁ - 12_N) designed for receiving or receiving and transmitting radio-frequency signals, N radiators (12₁ - 12_N) being meant for connection to common receiver, involves measurement of at least one characteristic of at least one signal received from at least two of mentioned radiators and control of at least one of parameters of phase and amplitude of signals received and/or signals to be transferred from first and at least second of mentioned radiators (12₁ - 12₄) depending on measured characteristic of signal being received. Set of antennas has N radiators (12₁ - 12_N)and antenna excitation device 40; each radiator has antenna excitation section (13₁ - 13_N) connected to antenna excitation device 40; N radiators (12₁ - 12_N) are designed for connection to common receiver through antenna excitation device 40 that has control means 47, 45, (42₁ - 42_N), (54₁ - 54_N)for at least one of phase and amplitude parameters of signals received and/or signals for transmitting first and at least second of mentioned radiators (12₁ - 12_N). Radio communication device has chassis, user's interface, and receiving circuits or receiving and transmitting ones connected to set of antennas.

EFFECT: eliminated blind sectors in directivity patters; improved adaptability of the latter to optimized transmit-receive operation.
