Characterization of a 8-Ports Vector Antenna for Measurement Applications

A wideband and radiation-pattern-reconfigurable vector antenna that presents eight ports is characterized for antenna measurement applications. This vector antenna can be advantageously employed either as a multi-polarized probe in a classical measurement set-up or as a reference antenna in a multi-probe antenna system with the test-zone-field (TZF) compensation method. Thank to the capability of polarization diversity inherent to vector antennas and to the radiation pattern reconfigurability of the proposed antenna, the complexity and time of the measurement process can be reduced.
