MICROSTRIP ANTENNA INCLUDING THAT FOR SATELLITE TELEPHONE COMMUNICATIONS Russian patent published in 1998 - IPC

FIELD: antenna engineering. SUBSTANCE: antenna has first insulating layer incorporating on one side grounding surface and on other side, first conducting substrate of desired shape. Second insulating layer is placed above first one on first substrate side and carries second conducting substrate of desired shape on its other side opposing first substrate. Third insulating layer is made above second one. Second conducting substrate is smaller in size than first conducting substrate. The latter is supplied with power from underside in at least one point located between its center and periphery. It will be good practice to connect first conducting substrate to grounding surface with through lead connected to power circuit set up in insulating substrate of triple-plate structure. EFFECT: provision for antenna operation in transmit and receive modes within extremely close frequency bands. 12 cl, 6 dwg
