1. A subarray in an active array used for transmission and reception of a microwave RF signal, said microwave signal being generated in an exciter, said subarray comprising:

  • a manifold to convey the microwave signal from the exciter;

    beam steering means, for steering the microwave signal received from the manifold;

    a transmit amplifier connected to the beam steering means, for amplifying the microwave signal prior to transmission;

    an antenna connected to the transmit amplifier, for propagating the microwave signal toward a target and for receiving a reflected microwave signal reflected from the target; and

    a receive amplifier, for amplifying the reflected microwave signal from the antenna;

    wherein the receive amplifier directs the reflected microwave signal to the beam steering means, which then transmits the reflected microwave signal to the manifold, which then transmits the reflected microwave signal to a receiving means, for interpreting and outputting the reflected microwave signal; and

    wherein discrete, active high-frequency RF components including the transmit amplifier, the receive amplifier, and the beam steering means are disposed on a plurality of planes aligned in a column so that the reflected microwave signal is transmitted vertically among the discrete, active high-frequency RF components disposed on the plurality of planes.
