The consideration of the relative permeability in the antenna design requires a more detailed analysis of its impact, together with the relative permittivity, on the antenna performance. The next statistical experiment analyzes the impact of these two parameters on the same major antenna outputs: resonant frequency fres , minimum return loss RL, maximum gain at the resonant frequency G, and the 10 dB bandwidth BW . The methodology used is the same as the one used for the loss tangent analysis and shown in Fig.
20 and they show that the return loss of the inkjet-printed antenna is slightly larger than the copper one. Overall a good agreement between the copper etched and the inkjet-printed antennas was observed despite the higher metal loss of the silver-based conductive ink. The radiation pattern was measured using Satimo’s Stargate 64 Antenna Chamber measurement system as shown in Fig. 21 and by using the NIST Calibrated SH8000 Horn Antenna as a calibration kit for the measured radiation pattern at 915 MHz.
29. In order to calculate the gain of the antenna from the measured results, a propagation model has to be applied. To determine which propagation model is suitable for our measurement setup, an investigation to whether any obstacles exist in the ﬁrst Fresnel zone of our wireless link setup was performed. Therefore, the maximum radius of the ﬁrst Fresnel zone has to be calculated. 4. 27: Prototype antenna (transmitter) and vector signal generator setup. in Fig. 30. 58 m. It is observed that r is lower than the heights of the transmitter and the receiver and since no object exists between them, the requirement of clearance of the ﬁrst Fresnel zone is satisﬁed.
