Abstract
An antenna apparatus for detecting an optimum directivity. The apparatus has an antenna capable of having plural directivities at predetermined directions; a scanning signal generator coupled to the antenna for generating a scanning signal for scanning the plural directivities from the first directivity to the last directivity; a signal level memory coupled to the antenna for memorizing plural memorized signals which are proportional to the output signal levels of the antenna at the plural directivities, respectively, when the plural directivities are scanned by the scanning signal; a detector coupled to the signal level memory memorized for detecting a maximum level memory signal from among the plural memorized signals after the scanning; and a controller coupled between the scanning signal generator and the detector for controlling the scanning signal generator in response to the maximum level memorized signal so as to fix the directivity of the antenna at the directivity corresponding to the maximum level memorized signal.
