An Inflatable Antenna Loaded on a Swimming Ring

This article proposes an inflatable antenna loaded on a swimming circle. The antenna uses PVC as the inflatable material, with a dielectric constant of 4 and a loss angle tangent of 0.01. Place metal strips on the surface of the swimming pool to achieve the radiation performance of the antenna. The input impedance of the antenna is 50 ohms, and it can generate multiple frequency bands suitable for various applications. The radiation pattern of the antenna is symmetric and exhibits excellent radiation performance. This antenna can locate the position of the swimming circle in real-time, making it highly practical. By controlling the inflation and deflation of the antenna, its size and weight can be effectively reduced, making it a promising technology with broad market prospects.
