Pressure parameter extraction equipment capable of working in ultra high temperature environment

An embodiment of the invention relates to the pressure parameter test technology field and especially relates to pressure parameter extraction equipment capable of working in an ultra high temperature environment. A resonance structure is a closed circular resonant cavity. A periphery is surrounded by a heat-resisting material outer wall 201. A bottom of the outer wall 201 is integrated with a medium cylinder 202. A top of the outer wall 201 is integrated with a layer of pressure sensitive medium diaphragm 203. A broadband miniature antenna 204 used for pressure parameter extraction and transmission is tightly pasted on the medium diaphragm 203. The broadband miniature antenna 204 is integrated with a tune short wire 205 and a coupling slit 206. A pressure parameter test equipment possesses a simple structure form, a small structure size and high pressure sensitivity. Sensitive structures are formed by passive units, which is convenient for using a specially-produced heat-resisting material. The equipment can work in the high temperature environment for a long time.
