An inflatable conical oscillator antenna

In this paper, an inflatable conical oscillator antenna is proposed. At present, the conical oscillator antenna has a larger size due to high gain requirements, resulting in a heavier weight, and the existing scalable oscillator antenna only reduces the size without reducing the weight. We propose an inflatable conical oscillator antenna for this purpose. The operating frequency band of this cone-shaped oscillator antenna is 1.4-4.1 GHz, achieving a wider frequency band and allowing for the transmission and reception of more signals. The antenna uses metal strips placed on the surface of inflatable film to achieve lightweight and contractible antenna, thus achieving portability. The antenna performance is comparable to pure metal, proving that inflatable antennas have good antenna radiation performance and can replace pure metal antennas. They can be applied in communication systems that require multiple movements.
