The core design leverages the flexibility, corrosion resistance, and insulation properties of rubber to protect the antenna while ensuring effective signal transmission. Rubber antennas are widely used in wireless communication fields such as mobile communication, the Internet of Things (IoT), and vehicle communication, performing excellently in complex environments due to their unique physical characteristics. A rubber antenna is a type of antenna that uses rubber as the outer sheath or substrate, combined with a metal conductor (such as copper or aluminum).
The working principle is based on the radiation and reception of electromagnetic waves. Under the influence of alternating current, the metal conductor inside the antenna generates an electromagnetic field, thus radiating electromagnetic waves. Conversely, when electromagnetic waves encounter the antenna, an alternating current is induced in the metal conductor, achieving signal reception. The rubber outer sheath primarily protects the metal conductor from corrosion and mechanical damage, without affecting the transmission of electromagnetic waves.
