Electromagnetic design aspects of packages for phased array modules that may incorporate monolithic antenna elements

It is pointed out that, where large floor area packages must be used and damping with lossy material is not acceptable, the electromagnetic design of MMIC (monolithic microwave integrated circuit) packages requires careful analysis for the minimization of cavity resonance effects. If monolithic antenna elements are to be used, then aspects of the antenna array design are directly relevant to package design and the suppression of resonances. The following issues are examined: basic package functions and features; MMIC module layout, package shape, and connections; electromagnetic design problems within packages; and the effect of antenna radiation on package design.<
