Printed dipole antenna

Abstract

Abstract PURPOSE:To simplify the constitution and to decrease the occupied area, by printing two dipoles on a dielectric substance board, twisting the dipoles and making them orthogonal with each other. CONSTITUTION:Dipoles 14a, 14b, 15a, 15b, parallel two-lines 16a, 16b and 17a, 17b, tapered baluns 18, 19, a ground conductor 20, and inner conductor 21, 22 are printed on the front and rear side of a dielectric substance board 13 having notches near the parallel two-lines 16a, 16b and 17a, 17b. Twisted parts B1, B2 are provided for the notches, and the dipoles 14a, 14b and 15a, 15b are tilted by 45 deg. each and they are made orthogonal with each other. Orthogonal electric field components E1, E2 of electromagnetic waves incoming from the direction A can be received at the dipoles 14a, 14b and 15a, 15b and its reception current can be obtained from coaxial plugs 23 and 24. Further, the same result can be obtained when the dipoles are twisted in an arbitrary angle.
