Background

Basalt fiber: continuous fibers drawn from natural basalt. The basalt stone material is melted at 1450-1500 ℃, and then is drawn at high speed by a platinum rhodium alloy wire drawing bushing to form continuous fiber. The pure natural basalt fiber is generally brown in color and has metallic luster. The basalt fiber is a novel inorganic environment-friendly green high-performance fiber material and is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, ferric oxide, titanium dioxide and the like. The basalt continuous fiber has high strength, and also has various excellent performances of electrical insulation, corrosion resistance, high temperature resistance and the like. In addition, the production process of the basalt fiber determines that the produced waste is less, the environmental pollution is less, and the product can be directly degraded in the environment after being discarded without any harm, so the basalt fiber is a real green and environment-friendly material. Basalt fibers are taken as one of four major fibers (carbon fibers, aramid fibers, ultra-high molecular weight polyethylene and basalt fibers) which are mainly developed in China, and industrial production is realized. The basalt continuous fiber has been widely applied in various aspects such as fiber reinforced composite materials, friction materials, shipbuilding materials, heat insulation materials, automobile industry, high-temperature filter fabrics, protection fields and the like.

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. This is the reciprocity theorem for antennas.
