Abstract :
A novel MMIC active antenna structure has been demonstrated by closely integrating a HEMT device and a slot antenna on opposite sides of a GaAs substrate. To our knowledge, this is the first time that such components have been integrated on the same MMIC. It is also the first time that circuit components have used both sides of an MMIC with via holes providing the through substrate connections. This active transmit antenna was developed for 30 GHz operation.
