This document details the characteristics and performance of the Small Sized Printed ILA Antenna (WES0118-01-APL915S-01) from Silicon Labs. It covers key aspects such as antenna dimensions, the necessity of an external matching network, and impedance measurements. The document also presents comprehensive radiation patterns in XY, XZ, and YZ cuts, with both horizontal and vertical receiver antenna polarization.
Furthermore, the document includes radiated harmonics measurements, ensuring compliance with FCC regulations. Range testing results are provided, outlining the achievable distances under various configurations and settings, including different data rates and power levels. Reference range measurements using a standard monopole antenna are also included for comparison. The document emphasizes the impact of hand effect and grounding environment on antenna performance, particularly in small remote applications.
Finally, the document provides an estimated indoor range based on TX power, sensitivity data, and a typical propagation factor for office environments, utilizing the Silicon Labs' range calculator.
