Abstract (en)

[origin: EP0422431A2] 2.1 It is intended to specify an angular-diversity system which permits reception of the transmitted signals with a low error probability during multipath propagation in a radio field. 2.2 A main beam lobe, which is oriented in the main propagation direction of the waves and consists of at least one wave type with a symmetrical field distribution, is generated in an antenna supply system (1, 2, 3, 4, 5, 6). Two sidelobes, which are spread in a plane with respect to the main beam lobe, are formed from waves polarised at right angles to one another, having an antisymmetrical field distribution. <IMAGE>
