A direct radiating phased array antenna is expected as a next generation communication antenna on the low earth orbit (hereafter LEO). A thermal control plate, Looped Heat Pipe plate (hereafter LCHP) made of a pulsating heat pipe (hereafter PHP., Fig.1), is promising for thermal device^<(1)>. It is applied to the antenna panel which is directly boarded a communication device of high heat flux density, that is a solid state power amplifier (hereafter SSPA), a digital beam forming (hereafter DBF), and so on. Two development models are manufactured; the one is a thermal verified model (1000mm×1300mm×2 pieces., Fig. 2) and the other is a coupon panel (708mm×708mm., Fig.3). In both the above LCHP are laid down the component side of the antenna panel opposite to RF radiation side. LCHP is double in PHP layer; the PHP fine tube of upper layer and that of the lower one are crossed at right angle each other. We obtain by vacuum test of the thermal model in LEO thermal environment that a temperature difference all over the LCHP side is a several degree C and a thermal conductivity of LCHP is at least from 10 to 20 times higher than one of a typical aluminum alloy. We also confirmed by a thermal test of coupon panel in temperature controlled air flow (ambient camber) and thermal vacuum test that the effective thermal conductance depends on a position of heater, it little depends on the inclination of LCHP, and an effective thermal conductance of the dissipation heat case is higher than the other heat cases (top heat case and bottom heat case).
