【0034】また樹脂パネルの内側に地板導体を固定一体化し、樹脂パネルの外側に放射導体を導電材のメッキまたは蒸着または塗布または印刷の手段を用いて形成することで板状逆Fアンテナを構成すると、アンテナ装置は樹脂製パネルに完全に一体化されるためにアンテナ装置の無線機の無線通信部との接続と無線機筐体の組立が一度に行えるために製造工程を削減できるとともに製造時間を短縮し、またアンテナ装置と樹脂パネルを一体化したことによりスペーサ部品等の固定部品を削減することができる。 Further the ground plane conductor is integrally fixed to the inside of the resin panel, constitutes a planar inverted F antenna be formed by means of plating or vapor deposition, or coating or printing of the conductive material to the radiating conductor to the outside of the resin panel Then, the production time with the antenna device can reduce the manufacturing steps for assembly of the connection and radio housing of the radio communication unit of the radio antenna apparatus can be performed at a time to be fully integrated into the fender panel it is possible to reduce the fixing parts such as the spacer component by a shortened and integrated an antenna device and a resin panel. また放射導体を導電材のメッキまたは蒸着または塗布または印刷の手段を用いて形成しているので薄型に製造できるため無線機筐体の外側に放射導体を配しても外観を損なうことがない。 The never disfiguring be arranged radiating conductor on the outside of the radio housing since the TFT can be formed thin because formed using a plating or vapor deposition, or coating or printing means of the electrically conductive material of the radiation conductor. なお地板導体についても導電材のメッキまたは蒸着または塗布または印刷の手段を用いることでより無線機の薄型設計ができるとともに製造作業性及び生産性が向上する。 Incidentally ground plane conductor manufacturing operations and productivity with more can thin design radios by using means of plating or vapor deposition, or coating or printing of the conductive material is improved also.

【0035】また樹脂パネルの外側に放射導体を導電材のメッキまたは蒸着または塗布または印刷の手段を用いて形成し、放射導体の表面に非導電性の表面保護部を設けることにより無線機が屋外で使用される場合において放射導体に水滴の付着を防止でき、水滴付着による放射導体の酸化を防止できるためアンテナとしての性能が劣化しにくく、また屋外での使用に耐えることができるので、設備機器に用いられる無線機に使用することができるとともに、板状逆Fアンテナの製造作業性及び生産性が向上する。 Further radio outdoor by a radiation conductor on the outer side of the resin panel formed by means of plating or vapor deposition, or coating or printing of a conductive material, a surface protective portion of the non-conductive surface of the radiating conductor in the case used can prevent the adhesion of water droplets to the radiation conductor, the performance of the antenna is less likely to deteriorate since it is possible to prevent oxidation of the radiation conductor due to adhering water droplets, also it is possible to withstand outdoor use, equipment it is possible to use the radio for use in, thereby improving the manufacturing operations and productivity of a planar inverted F antenna.
