ABSTRACT:
Methods of fabricating air-dielectric true-time-delay, continuous transverse stub array antenna. The first method uses conventional machining or molding techniques to fabricate layers of plastic with desired microwave circuit features. The plastic layers are then metalized, assembled (aligned) and joined together, such as by using ultrasonic welding techniques. Readily available metalization and ultrasonic welding techniques exist that may be used. The second method uses sheets of metal, into which microwave circuit features are fabricated, such as by machining. The layers are then assembled (aligned) and joined together, using one of several available processes, such as an inert gas, furnace brazing technique, for example.
