Abstract :
An oscillating antenna allowing binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK) is demonstrated. The modulating signals are applied to a PIN diode switch and an injection-locked oscillator. Experimental results are presented, including constellation diagrams of the radiated signal and typical waveforms of demodulated signals
