Deep Integration Antenna Array: Design Philosophy and Principles

An active integrated antenna array is designed through a new design low called Deep Integration. Amplifier output currents are combined to synthesize the optimal antenna current distribution to produce the desired radiation characteristics. The electromagnetic field from a cluster of amplifiers is power-combined in low-loss (air) dielectrics inside a single antenna element to increase the total radiated output power. These elements can be combined in an array to further increase radiated power. Such solutions are highly compact in size and capable of delivering high Effective Radiated Power (ERP), which is particularly important in the area of mm-wave integrated circuit design for wireless applications. A simulation example is provided of a Deep Integration antenna array, demonstrating the design philosophy and principles.
