Abstract :
The design of a stable narrowband active antenna oscillator at 0.9-1.8 GHz is reported. Novel use of a MMIC RF amplifier as the active device with two coupled patch resonators is presented. The design is based on EM-simulated antenna scattering parameters and manufacturer device measurements; this technique is confirmed by measurement of physical prototypes. Frequency tuning by varying the geometry or the supply voltage is observed and quantified.
