1.1.Test Setup1.1.1 VNA Test Setup

S parameter measurements (S11) were performed using an KeySight E5071C Network Analyzer and previously described tests fixtures. The isolation between antennas is also tested. The testing was performed with apparatus in free space.

1.1.2 Anechoic Chamber Test SetupThe gain of the antenna was measured in the anechoic chamber(ETS-3D). The chamber provides less

than –30 dB reflectivity from 400 MHz through 6 GHz. The chamber size is:7m*4m*3m.The measurement results are calibrated using a leaky wave horn standard. We can measure the antenna gain and efficiency accurately.
