This document provides a comprehensive antenna specification for the IBM 2.4GHz wireless device. It details key parameters such as center frequency, maximum gain, polarization, and azimuth beam pattern. The antenna is designed for the ISM 2.4 GHz band and exhibits an omni-directional azimuth beam pattern, making it suitable for various wireless applications.
The specification includes detailed measurements at three center frequencies: 2403.65 MHz, 2441.65 MHz, and 2479.65 MHz. For each frequency, the document presents horizontal and vertical polarization patterns, along with corresponding gain values. The antenna's physical dimensions, including a length of 17.8 mm, are also specified.
The document also includes antenna radiation patterns, which are presented in both horizontal and vertical polarizations for each of the three center frequencies. These patterns provide valuable insights into the antenna's performance and coverage characteristics. The data presented in this document is essential for understanding and optimizing the performance of the IBM 2.4GHz wireless device.
