PURPOSE:To easily heat a structure body by a heating element, to prevent ice coating of a radar antenna, etc. which are used in a very cold place, and to prevent a fault of efficiency and function, and generation of a breakdown accident, by providing a thermal conduction line between the structure body of an antenna, and its resistance material. CONSTITUTION:Air layer between the outside surface of structure bodies 5-7 of an antenna 1, and a resistance material 9 of a heating element 8 is removed, its space is filled with a thermal conduction material, and a conduction line 14 is formed by connecting the outside surface of the structure bodies 5-7 and the resistance material 9. This conduction line 14 is utilized as a passage for transmitting the heat which has been generated by the resistance body 9, to the structure bodies 5-7. This thermal conduction material is made of greaselike or resinlike liquid which has mixed metallic powder, and its material is injected into between the structure bodies 5-7 and the surface of the resistance material 9, and is solidified. Said structure bodies 5-7 are made transmitting and receiving bodies for catching electromagnetic waves from an antenna and transmitting a signal current to a communication equipment 2, and radiating the electromagnetic waves induced by the signal current from the communication equipment 2, in the air, the resistance body 9 is heated by a heating electric power supply 3, and ice coating of the structure bodies 5-7 in a very cold place is prevented. |
