Design Considerations of an Active Integrated Antenna with Negative Resistance Transistor Oscillator
The design of an active integrated antenna with negative resistancetransistor oscillator has been described. Simple but reasonablyaccurate analysis of oscillation start-up and steady state operatingfrequency prediction is presented. The active antenna prototype wasmanufactured and its operating freq...
