Publication number: 20230291120Abstract: Antenna-directivity adjustment is implemented by adjusting an antenna of a radio communication device in horizontal, vertical, and rotation angles in response to received-signal levels and cross-polarization discriminations. Received-signal levels (RSL) are measured by moving the antenna of the radio communication device in horizontal and vertical directions. Cross-polarization discriminations (XPD) are calculated according to received-signal levels (RSL) measured by changing vertical polarization and horizontal polarization on a transmit side and a receive side with the antenna when rotated and an interference level measured between vertical polarization and horizontal polarization. An antenna direction is adjusted to maximize received-signal levels and cross-polarization discriminations.Type: ApplicationFiled: February 6, 2023Publication date: September 14, 2023Applicant: NEC CorporationInventor: Takahiro Okano
