Abstract
A wireless communication apparatus includes a signal terminal which receives a transmitting signal, N antenna elements, where N is an integer greater than or equal to 2, a first amplifier including first input and output terminals, and N second amplifiers including N second input and output terminals coupled to the N antenna elements, respectively. The first amplifier amplifies the transmitting signal received from the signal terminal via the first input terminal with a gain which is weighted and adjustable according to a first weight. The N second amplifiers amplify the amplified transmitting signal received from the second output terminal via the N second input terminals with gains which are weighted and adjustable according to N second weights. The amplified transmitting signal, amplified by the N second amplifiers, is output to the N antenna elements via the N second output terminals.
