This document presents the unlicensed band antenna gain information for the Samsung SM-L500 device. The report includes details on the antenna gain measurement procedure, the test setup, and the radiation patterns. The device features a front metal PIFA antenna for the 2.4GHz band. The antenna gain measurements were conducted in a reverberation chamber using a network analyzer and calibrated antennas.
The report provides specific gain values for various frequencies within the 2.4GHz band, including 2400MHz, 2412MHz, 2437MHz, 2451MHz, 2472MHz, and 2485MHz. The test setup involved assembling the antenna into the fully assembled and operating A3LSML500 Smart Watch. The antenna was tested in free space in the anechoic chamber in the H, E1 and, E2 planes. The radiation patterns are measured at the center of transmit and receive bands.
The document also includes information about the calibrated equipment used during the testing process, such as the TX antenna, reference antenna, and network analyzer. The tests were conducted on 2025.05.08 by MH Jeong. The report concludes with radiation plots for the maximum gain plane at different frequencies.
