PROBLEM TO BE SOLVED: To amply reduce data transmission errors, in the case of especially using an antenna system for data communication by enhancing shield performance with respect to a noise electric field and to enhance the anti-vibration performance and resistance to shock by improving the rigidity of the entire antenna system. SOLUTION: A conductive pattern for shielding electric field is formed respectively to an upper side base 1 and a lower side base of this antenna system, and side bases 3-6 with a similar shield conductor pattern formed to them are placed, so as to cover openings formed between ends of the two upper and lower bases. Furthermore, projections (p) are formed to the ends of the two upper and lower bases, holes to be engaged with the projections (p) are made to the side bases 3-6 and the entire system is integrated by soldering the fitted parts.
