The invention relates to an aperture antenna array, and to a method and a system for determining the location, the tracking, the detection and the control of the access of people and objects, with a determined attribute, in a determined topological space and at a determined time, by means of an aperture antenna array that measures the angles of arrival and departure of radiofrequency transmissions. The antenna array is circular, flat and sectorial and forms part of a marker radio beacon which also comprises a transceiver, an omnidirectional antenna, a microcontroller, a battery and the circuitry. The antennae are arranged in a radial form on a circle pertaining to a plane of symmetry and cover 360° in the preferred embodiment, with the apertures facing outside the circle and the related waveguides and throats thereof towards the inside. There is a tube in the centre of the array, the longitudinal axis of said tube being perpendicular to the plane, where the intersection of the two corresponds to the centre of the array. |
