PROBLEM TO BE SOLVED: To solve the conventional problem of an active phased array antenna unable to have a heat dissipating structure that is thin and light in weight, when using a high-output power amplifier which releases a large amount of heat.;SOLUTION: An active device 9-6 and an excitation antenna element 9-1 are formed into an excitation active antenna 9 of integral structure, the excitation active antenna 9 is disposed on a metal plate 7, and the metal plate 7 has a structure, formed of hollow pipes which are joined together in parallel crosses. A coupling antenna plate 4, on which coupling antenna elements 3 are formed, is arranged above the excitation active antenna 9, and a radiation antenna plate 2, on which radiation antenna elements 1 are formed, is arranged above the coupling antenna plate 4, so that a power is fed to the radiation antenna elements 1 from the coupling antenna elements 3 by stabling electromagnetic coupling.;COPYRIGHT: (C)2003,JPO
