A simple frequency‐selective load in the form of a compensating network is attached to an oscillator‐type transmitting active integrated antenna (AIA) to suppress undesired low‐frequency oscillations and to improve the robustness of the oscillator. Although the input impedance of the active device (transistor) remains unchanged at the upper frequencies, it changes drastically at the lower frequencies. © 2001 John Wiley & Sons, Inc.
