A dual mode missile seeker system utilizing an infrared transparent radar tenna is disclosed. The infrared transparent radar antenna is mounted in front of and on the same axis as the infrared detector within a missile dome. The radar antenna includes spaced apart patches of infrared transparent semiconductor material and a ground plane of the same material deposited on opposite sides of an infrared and microwave transparent dielectric substrate for transmitting and receiving microwave radiation and for shielding the infrared detector array mounted behind. A radome or separate lens redirects incoming infrared radiation so as to pass through the radar antenna and focus on the infrared detector array.

[ What is claimed as new and secured by Letters Patent of the United States is:] [1.] An infrared transparent, microwave radiation radiating and receiving antenna comprising:a substrate of infrared transparent dielectric material having two opposing surfaces;a ground plane of semiconductor material transparent to infrared radiation within a preselected frequency band deposited as a thin film on one of the opposing surfaces, said ground plane adapted to block all incoming electromagnetic radiation outside of the preselected frequency band;a plurality of patches of the same semiconductor material as said ground plane material deposited in spaced apart relationship on the second of the opposing surfaces and being the same thickness as said ground plane, said patches adapted to be electrically pulsed for radiating microwave radiation outwardly from the antenna, said patches further adapted to receive incoming microwave radiation and generate an electrical signal in response thereto.
