An efficient oscillator active antenna has been designed and demonstrated. The circuit radiates a clean spectrum, and transmits a stable signal with fairly good radiation patterns. The cross-polarization levels were better than 10 dB below copolarization. The antenna provides a dcαRF conversion effi
