Abstract: An antenna module includes a frequency modulation radiator and a T-coil radiator electronically connecting to the frequency modulation radiator. The T-coil radiator and the frequency modulation radiator are made of conductive nano material. The present further discloses a wireless communication device using the antenna module.

Abstract: A method to synthesize a chlorine dioxide block remover in a well is described. The method includes dissolving a chlorate aqueous solution and some acidic substances in water and to produce a hydrogen ion. The chlorate aqueous solution and acidic substances are quickly injected into the well by an injection pump, so they react with each other and produce chlorine dioxide. The synthesis of the chlorine block remover in the well removes oil layer blocks induced by polymers and microbes, while reducing the risk of explosion caused by leaked chlorine dioxide, and reducing the corrosion of equipment and pipes caused by chlorine dioxide.
