Abstract

A phased array antenna system with adjustable electrical tilt includes an array 62 of antenna elements 621 to 6210. It has a splitter 44 dividing a radio frequency (RF) carrier signal into two signals between which a phase shifter 46 introduces a variable phase shift. Further splitters 52 and 54 divide the relatively phase shifted signals into two sets of five signals. Four of each of the sets of five signals are vectorially combined in a network of 180 degree hybrid couplers 601 to 604. This provides vector sum and difference components which together with the fifth members of the sets are fed to respective fixed phase shifters 56, 58 and 641 to 6410. The phase shifters 641 to 6410 provide signals which are appropriately phased for use as phased array drive signals for respective antenna elements 621 to 6210. Adjustment of the single phase shift provided by the variable phase shifter 46 changes the angle of electrical tilt of the entire antenna array 62.
