Abstract (en)

[origin: EP0654845A1] The invention relates to an adaptable dipole-type radiating element consisting of a substrate plate (1), of a feeder line (2) situated on the lower face of the said substrate plate (1), and of a metal deposition (3) situated on the upper face of the said substrate plate (1) and substantially T-shaped: the horizontal bar of the said T consisting of two lateral strands (5, 6) separated by a coupling slot (7), and the vertical bar (11) of the said T constituting an earth plane for the said feed line (2), the said lateral strands (5, 6) constituting the radiating part of the said radiating element. According to the invention, the said feed line (2) has a first end portion (9) extending along an axis intercepting the axis of the said coupling slot (7) and extending from the said axis of the coupling slot by a first variable length (l1), the said slot (7) has a second end portion (10) extending from the axis of the said first end portion (9) of the feed line by a second variable length (l2), and the radiating element comprises first and/or second variable-capacitance means, the said first variable-capacitance means being connected between an earth plane (6) and the end of the said feed line (3) situated in the said first end portion (9), the said second variable-capacitance means being connected between an earth plane and the end of the said slot situated in the said second end portion. <IMAGE>
