摘要：
An antenna module is described for configuring a mobile device, e.g. a smartphone, to locate an animal wearing a radiofrequency (RF) transmitter, the module comprising: a directional antenna structure, the antenna structure including a plurality of antenna elements configured to generate a directional radiation field； at least one radio frequency (RF) receiver connected to the directional antenna structure； and, a controller configured to control the RF transceiver and a mobile device interface for providing communication with the mobile device, the controller being configured to execute the steps of: receiving one or more time series of beacons signals broadcasted by the RF transmitter that is within the directional radiation field of the directional antenna structure； determining distance estimates for beacon signals in the one or more time series, a distance estimate being determined by the antenna module on the basis of a signal strength and/or a signal quality of a detected beacon signal.
