PHASED ARRAY ANTENNA CALIBRATION METHOD AND PHASED ARRAY ANTENNA CALIBRATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18025644 titled 'PHASED ARRAY ANTENNA CALIBRATION METHOD AND PHASED ARRAY ANTENNA CALIBRATION SYSTEM
Simplified Explanation
The patent application describes a method for calibrating a phased array antenna.
- The phased array antenna consists of multiple transmission modules and a reception module.
- Each transmission module includes a phase shifter, an amplifier, and a transmission antenna.
- The reception module includes a reception antenna.
- The method involves receiving a reflected wave, which is a radio wave transmitted from the transmission antenna of each transmission module and reflected outside the phased array antenna.
- Based on the amplitude and phase of the reflected wave received, the method adjusts the phase shifter and amplifier of each transmission module.
Original Abstract Submitted
A method for calibrating a phased array antenna is provided. The phased array antenna includes multiple transmission modules each including a phase shifter that changes a phase of a high frequency signal output from a signal source, an amplifier that amplifies an amplitude of the high frequency signal, and a transmission antenna that converts the high frequency signal into a radio wave, and a reception module including a reception antenna. The method includes a step of receiving, by the reception antenna, a reflected wave that is a radio wave transmitted from the transmission antenna of each of the multiple transmission modules and reflected outside the phased array antenna, and a step of adjusting the phase shifter and the amplifier of each of the multiple transmission modules based on an amplitude and a phase of the reflected wave received.
