Unlicensed Band Antenna Gain
Model: SM-A176B/DS, SM-A176B
FCC ID: A3LSMA176B
This document presents the antenna gain data and radiation pattern test results for the Samsung SM-A176B/DS and SM-A176B mobile devices, identified by FCC ID A3LSMA176B. The antennas were tested for Gain and Efficiency, assembled into the fully assembled and operating handset. Testing was conducted in free space within an anechoic chamber, measuring radiation patterns in the H, E1, and E2 planes at the center of transmit and receive bands.
