Abstract:

The introduction of 5G technologies is pushing research in mobile communications to millimeter waves. However, sub-6 GHz frequency range as a part of the 5G standard provides excellent wave propagation properties and more capacity due to new usable frequency ranges. This paper introduces a design for picocell base station 2x2 antenna array with integrated signal injection network for transceiver calibration. Operation frequency range is from 2 to 6 GHz. The antenna array with calibration board has better than -6.3 dB active reflection coefficient and efficiency higher than -3 dB. Calibration network provides 29 dB coupling.
