Reliable and cost-effective packaging of monolithic microwave integrated circuits (MMICs) is an important aspect of the design of phased array systems. At millimeter wavelengths, where small dimensions make machining and assembly a complex matter, th

An electric field integral equation method is applied to a metal strip antenna on an electrically thick dielectric substrate of finite size in a uniform infinite array environment. An efficient solution is found using the method of moments. Metal str

The Helicon Double Layer Thruster is a new type of magneto-plasma thruster which combines the helicon technology for an efficient coupling of the electrical power to the plasma and a current-free double layer (formed spontaneously in the physical and

An antenna consisting of a single wire connection from a source to a half-wavelength dipole above a ground plane is studied. With the inherent simplicity of the structure in mind, and the frequent need to connect a dipole antenna to an unbalanced out

Mechanisms giving rise to cross-polarization by substrate-supported metal strip antennas are investigated, and a method for reducing cross-polarized radiation is presented. It is shown that cross-polarized radiation from substrate-supported metal str

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 minimizati

A flexible technique has been developed to analyze small size finite arrays by means of the finite array periodic Green's function. It attempts to improve the accuracy of the results by iteratively re-defining a better window function. Using a relati

A design method for a coupled-patch oscillator array has been proposed and the operation of the oscillator explained. The design is compatible with monolithic technology and is not restricted to a particular class of antenna element. Alternative ante
