(2) is a dielectric substrate integrally molded with the feed line, one end of the internal conductor (6) of the feed line is connected to the antenna element, and the other end is connected to the connector (4b). Ru. To manufacture such an antenna device, 1. For example, the antenna element fil and the internal conductor (6) are fabricated by integral molding or welding, and a dielectric material is then formed using a mold having a desired shape. After that, the base plate and the outer conductor of the feed line are formed by means of vapor deposition or the like. By integrally molding the antenna with a dielectric material in this manner, the reliability of the antenna is improved due to the reduction in the number of connecting parts and the reduction in the number of two parts. Furthermore, by using a heat-resistant d%i material such as bath-fused silica as the dielectric substrate (2), the antenna as a whole has heat resistance. The present invention can be applied to all coaxially fed antenna elements such as microstrip, spiral, short back fire, dipole, and cross dipole antenna elements. Heat-resistant dielectrics that can withstand temperatures of 1000°C or higher include, for example, bath-fused silica (TL) or ceramics.
