Abstract (en)
[origin: DE19929879A1] The invention relates to a helical antenna (1) which can be supplied with various radiating characteristics in different modes. The helical antenna (1) comprises four electrically conductive helical limbs (11, 12, 13, 14) which are guided in an approximately parallel manner. The helical limbs (11, 12, 13, 14) are connected via their respective inner helical limb ends (5, 6, 7, 8) to a coplanar line (2) for supplying and/or receiving signals.
