This document presents a detailed technical diagram of a 7-inch tablet antenna. The drawing includes various views of the antenna, including top, side, and isometric perspectives, along with cross-sectional views (A-A and B-B) to illustrate internal construction. Key dimensions are provided, with a note indicating that further dimensions for the 0.8mm coil can be found on the following page.
The antenna's electrical characteristics are specified, including a gain of 2 dBi. The document also details the specifications for the first layer coil (height 1.4mm), which is a low-frequency coil operating at 125kHz. It has a wire diameter of 0.1mm and an inductance of 216uH ±1% at 125kHz. The document emphasizes the importance of testing the inductance at the specified frequency and ensuring the coil is kept away from metallic objects during testing.
General tolerances are provided, and the drawing includes information about the materials used, the quantity of parts, and the finishing. The document was created on September 5, 2023, and includes the drawing number P001.
