Swivel low cost prototype and Automatized Measurment Setup to Determine 5G and RFID Arrays Radiation Pattern

Swivel low cost prototype using an alternative measurement setup with one pair of identical antennas to obtain the radiation pattern for millimeter wave antennas and antenna arrays applied to 5G and RFID services is proposed. The prototype uses a stepper motor controlled by Arduino Uno, that allows 360° rotation. The measurement setup uses a Swivel Prototype where the transmitter antenna is connected to a signal generator and the receiver antenna is connected to a signal analyzer, both of them using GPIB-USB control interface. LabVIEW is used to control the equipment and it measures the power reception level. Moreover, Matlab in the same LabVIEW VI is used to plot the radiation pattern in rectangular and polar forms. The simulated and measured results are compared and validated, both in a real environment and an anechoic chamber.
