Document Type and Number:
Japanese Patent JP2018165622
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna measuring apparatus capable of easily specifying an excitation state such as amplitude and phase of an antenna element in an array antenna.SOLUTION: The antenna measuring apparatus includes: a transmission unit (100) connected to a plurality of antenna elements (110) including an antenna element to be measured and for causing the antenna element to be measured to transmit a radio signal as a transmission signal; a reception unit (300) having a reception antenna for receiving the transmission signal output from the antenna element to be measured as a reception signal; and a lens (200) located between the antenna element to be measured and the reception antenna and converging the transmission signal from the antenna element to be measured toward the reception antenna.SELECTED DRAWING: Figure 1
