Abstract
A method of testing an antenna array includes: receiving a probe needle set and a shielding structure, wherein the shielding structure includes an array of conductive pads. The antenna array includes a substrate and an array of antenna devices. Each of the antenna devices includes: a first and a second slits; a first and a second signal ports; a first and a second feed lines. The first and second feed lines have different line lengths; and a radiation element. The method further includes: causing the shielding structure to cover the radiation element of at least one antenna device; and causing the probe needle set to contact the first and second feed lines for testing the at least one antenna device.
