Circular active integrated antenna with push-pull oscillator

In this paper, a new oscillating circular patch antenna with two bipolar transistors operating in push-pull mode is presented. By using a circular instead of a rectangular patch, the stability of the operating frequency is increased and second-harmonic radiated power is decreased. High radiated powe...

Zusammenfassung:In this paper, a new oscillating circular patch antenna with two bipolar transistors operating in push-pull mode is presented. By using a circular instead of a rectangular patch, the stability of the operating frequency is increased and second-harmonic radiated power is decreased. High radiated power and very linear frequency tuning are observed. The radiation patterns show no degradation due to patch modifications.
