Abstract (en)
Antenna with multiple elements capable to overcome the rapid variations in the power received in urban areas and inside buildings. Said antenna consists essentially of radiation elements arranged at equal distance from each other , on a circumference having a diameter ranging from 1/4 to 1/3 of the minimum wave length in the used band, with a flat conductor, these radiation elements having a cylindrical or conical shape. The advantage of the invention resides in the fact that it eliminates the quick variations in the power received in mobile radios. The invention relates to the technical field of microwaves and finds its most suitable application in the field of telecommunications in urban areas. <IMAGE>
