This document provides a comprehensive overview of an internal antenna, including its specifications and radiation patterns. The antenna, model R90, operates within the 2400-2500MHz frequency range and is manufactured by Shenzhen Yuntian Intelligent Terminal Co.,LTD. The antenna's peak gain is 0.98dBi.
The document includes detailed antenna photos showcasing its dimensions using digital calipers. Furthermore, it outlines the test equipment and conditions used for evaluating the antenna's performance, including VSWR measurements with an Agilent E5071B and passive efficiency testing using Agilent Technologies E5071B. The test environment and methods are described, referencing the dark room specifications (ETS-743) and the equipment used for TD-SCDMA, LTE-TDD/FDD-SCDMA, and WCDMA/GSM/CDMA testing.
The document presents antenna radiation patterns at 2400MHz, 2450MHz, and 2500MHz, providing visual representations of the antenna's performance in X, Y, and Z planes. These patterns offer insights into the antenna's directional characteristics and signal strength distribution.
