Abstract
The invention relates to a receiving antenna sensitive to nonuniform action of electromagnetic waves and belongs to the technical field of electromagnetic wave. The main part of the receiving antenna comprises a metal wire, a diode and a resistor, wherein the metal wire is exposed to electromagnetic wave irradiation. Circuits are led from the two ends of the metal wire into a shielding material and connected, and two output ends are led from the connection point; output from one output end is carried out through the diode, and output from the other output end is carried out through the resistor. When the receiving antenna works, the metal wire is subject to electromagnetic wave irradiation, and if the electromagnetic wave action on the metal wire at any time is uniform, the output signal of the antenna is very weak; and contrarily, the output signal of the antenna is relatively strong. Therefore, the antenna is sensitive to the nonuniformity of electromagnetic waves.
Description
Goal of the invention the present invention relates to a kind of to the responsive reception antenna of the inhomogeneous effect of electromagnetic wave; When this antenna exposed parts receives electromagnetic irradiation; If at any one time on the exposed parts of antenna every bit to receive electromagnetic effect identical, then the signal of antenna output very a little less than; Otherwise the signal of antenna output is stronger.The electromagnetic wave effect that the exposed parts of antenna receives is inhomogeneous more, and the signal of antenna output is strong more.This antenna can be applicable to aspects such as electromagnetic reception and detections.
There is the demand that electromagnetic wave is received and detects in background technology in the plurality of applications field; Wherein, Existing wire antenna technology is directly utilized the polarization of ele effect and is worked, and generally antenna has maximum output signal when polarization of ele is consistent with the wire antenna direction.The wire antenna technology is widely used through years of development, can satisfy the demand of most application scenarios basically.But also have following problem: hope that sometimes wire antenna is only responsive to electromagnetic inhomogeneous effect, existing wire antenna can't satisfy this requirement.
Result for retrieval shows, do not find to the problems referred to above, to the bibliographical information of the responsive reception antenna of the inhomogeneous effect of electromagnetic wave.The present invention adopts specially designed antenna, addresses the above problem, and satisfies the responsive requirement of electromagnetic inhomogeneous effect.
Summary of the invention the purpose of this invention is to provide a kind of to the responsive reception antenna of the inhomogeneous effect of electromagnetic wave, and the simple antenna structure that it utilizes metal wire, diode and resistance to combine realizes the responsive characteristic of electromagnetic inhomogeneous effect.
The present invention addresses the above problem the technical scheme that is adopted: a kind of its main part comprises a metal wire, a diode and a resistance to the responsive reception antenna of the inhomogeneous effect of electromagnetic wave, and metal wire is accepted electromagnetic wave irradiation.In the two ends lead-in wire entering barrier material of metal wire, connect, draw two outputs from tie point; One of them output is through a diode output, and another output is through a resistance output.Making the electromagnetic wave irradiation metal wire during work, is uniformly if receive electromagnetic effect at any one time on the metal wire, and promptly the electric current on the metal wire is uniformly, then the output signal of antenna very a little less than; Otherwise the output signal of antenna is stronger.Like this, this antenna is responsive to electromagnetic inhomogeneous effect.
The invention has the beneficial effects as follows: this antenna is responsive to electromagnetic inhomogeneous effect, can be applicable on the equipment such as responsive reception of electromagnetic incident direction, polarised direction and detection, and this antenna structure is simple; Be convenient to make; Cost is low, and is easy to use, helps practical application.
