Abstract: The present invention provides phased array antenna apparatus (200) for operation in frequencies above six gigahertz. The apparatus (200) comprises: a plurality of sub-arrays (208) together configured to form a phased array antenna, each sub-array (208) comprising at least four antenna elements (220), each antenna element (220) for receiving an input signal from the sub-array (220) and comprising: an antenna (230) for transmission of the input signal; and a signal modification component (222) to adjust a phase of the input signal during propagation to the antenna (230); and a plurality of power amplifiers (212), wherein each sub-array (208) is provided with a one of the plurality of power amplifiers (212), wherein each sub-array (208) is arranged to be provided with an amplified input signal, and each antenna element (220) of the sub-array (208) is configured to be provided with the amplified input signal of the respective sub-array (208) as the input signal to the antenna element (220), and wherein the power amplifier (212) for each sub-array (208) is configured to receive a phased array input signal for amplification and to output the respective amplified input signal to the respective sub-array (208). The power amplifier (212) for each sub-array (208) may be physically separate and distinct from each sub-array (208).
