Abstract

The invention belongs to a microwave and optical co-aperture antenna technology, and relates to a millimeter wave transmission and optical reflection dual-mode structure. The structure comprises an optical dielectric substrate (1) and is characterized in that the transmission rate of an optical reflection film (2) on a millimeter wave is not less than 98%, and the back of the optical reflection face of the optical dielectric substrate (1) is a frequency selection structure (3). The invention provides the millimeter wave transmission and optical reflection dual-mode structure to satisfy the needs of millimeter wave transmission and optical reflection.

Description

technical field [0001] The invention belongs to microwave and optical common-aperture antenna technology, and relates to a millimeter-wave transmission and optical reflection dual-mode structure. Background technique [0002] Frequency Select Surface (FSS for short) has a wide range of applications in both military and civilian applications. At present, the structure of using FSS to form a dual-frequency antenna is as follows: an FSS structure is set on a metal substrate, and a through hole on the metal substrate is used as a unit of the FSS structure. The reflective surface of the metal base reflects electromagnetic waves of one frequency band, and at the same time, the metal base transmits electromagnetic waves of another frequency band. Its disadvantages are: insufficient metal retention area, waste of caliber, resulting in low optical reflectivity, and cannot form a dual-mode structure of millimeter wave transmission and optical reflection.
