Abstract: The present disclosure provides a positive-pressure-withstanding high-power flat evaporator, processing methods thereof and a flat loop heat pipe including the evaporator. The evaporator includes a housing, and reinforcing ribs and a capillary wick which are positioned inside the housing, and the arrangement of the reinforcing ribs can ensure that the strength of the whole evaporator is capable of withstanding positive pressure. The capillary wick is composed of four parts, namely, an evaporating wick, a heat insulating wick, a sealing wick and a transfer wick. Through the large permeability of the transfer wick, liquid supply with low flow resistance can be realized, the heat transfer capability of the loop heat pipe is greatly improved, and the problems of long liquid supply path and large flow resistance caused by a large-area evaporator are solved.

Abstract: Disclosed are a low-frequency band dipole unit, a multi-frequency band array antenna and an adjustment method therefor. The low-frequency band dipole unit includes a first microstrip dipole arm (1), a second microstrip dipole arm (2) and a support structure (3). The first microstrip dipole arm (1) and the second microstrip dipole arm (2) are each in a T-shaped thin arm structure with two vertical arms upwards, each have a thickness in the order of millimeters, and are each in a straight line when viewed from above. The support structure (3) has a slot structure for clamping and supporting the first microstrip dipole arm (1) and the second microstrip dipole arm (2). The multi-frequency band array antenna has a plurality of columns and/or quasi-columns therein, and at least one column or quasi-column of the plurality of columns and/or quasi-columns is composed of the foregoing low-frequency band dipole units completely. The low-frequency band dipole unit has weak coupling and low blocking characteristics, is flexibly nested, and has a great arrangement freedom. The multi-frequency band array antenna has good arrangement freedom and beam adjustment freedom.
