Antenna system
An antenna system comprises an antenna assembly (102) having antenna elements (E1-E8) mounted upon an antenna carrier and arranged in at least two sub-arrays (100A, 100B). Each sub-array (100A, 100B) includes one or more antenna elements (E1-E8). The system (100) also includes control means (104) ar...

| Zusammenfassung: | An antenna system comprises an antenna assembly (102) having antenna elements (E1-E8) mounted upon an antenna carrier and arranged in at least two sub-arrays (100A, 100B). Each sub-array (100A, 100B) includes one or more antenna elements (E1-E8). The system (100) also includes control means (104) arranged to control electrically the phase of signals supplied to at least one of the sub-arrays (100A, 100B) from a location remote from the antenna assembly (102). The control means (104) adjusts the phases of signals supplied to respective sub-arrays (100A, 100B). A mechanical phase adjustment arrangement (150E1-150E8) is provided for further adjusting the phase of signals supplied to each antenna element (E1-E8). |
