A wide-angle null-fill antenna with no null in the depression angle range, an omni antenna using the same, and radio communication equipment. A null-fill antenna comprises a first antenna array including antenna elements arranged with a prescribed point as the center, and a second antenna array having amplitude characteristics substantially equal to those of the antenna elements forming the first antenna array. The first antenna array is excited so that the excitation amplitude distribution is to have symmetry with respect to the prescribed point, while the excitation phase distribution is to have point symmetry with respect to the prescribed point. The phase center of the first antenna array is substantially coincident with that of the second antenna array.

Antenne à grand angle avec élimination du rayonnement zéro sans rayonnement zéro dans la plage d'angles de dépression, antenne omnidirectionnelle aux capacités similaires et équipement de radiocommunication. L'antenne avec élimination du rayonnement zéro est constituée d'un premier réseau d'antennes comprenant des éléments d'antenne disposés autour d'un point central préétabli et d'un second réseau d'antennes dont les caractéristiques d'amplitude sont essentiellement les mêmes que celles des éléments d'antenne qui forment le premier réseau d'antennes. Le premier réseau d'antennes est excité de façon à ce que la distribution d'amplitude de l'excitation soit symétrique par rapport au point préétabli et que la distribution de la phase d'excitation soit symétrique par rapport au point de symétrie préétabli. Le centre de phase du premier réseau d'antennes coïncide presque complètement avec celui du second réseau d'antennes.
