This document provides a comprehensive antenna specification for devices manufactured by Zhongshan Yuanying Lighting Technology Co., Ltd. The specification details key parameters such as antenna type, center frequency, maximum gain, polarization, and impedance. The antenna is described as a "Type_2_single wiggle Antenna" with an omni-directional azimuth beam pattern.
The document includes specific data for three center frequencies: 2402 MHz, 2441 MHz, and 2480 MHz. For each frequency, the maximum gain is provided, along with horizontal and vertical radiation patterns. The polarization is horizontal, and the impedance is 50 Ω. The antenna length is 15.8mm. The document also includes a detailed antenna photo with length measurements in millimeters.
The tests were conducted on 2019-04-14 using a vector network analyzer - R&S ZVB20. The radiation patterns are presented in polar plots, showing the signal strength at various angles for both horizontal and vertical polarities. The maximum, average, and minimum gain values are provided for each frequency and polarity.
