Abstract :
This paper reports on the design of a broadband lens-integrated differentially-driven polarization-diversity circular slot on-chip antenna for a 240 GHz power source in a SiGe HBT technology. The slot is excited by 2 pairs of orthogonal sectorial patch probes located 90° apart along the slot circumference, whereby the mutual coupling between them is exploited to extend the antenna operation bandwidth. The antenna was simulated to provide a 10-dB impedance bandwidth of 150-500GHz with consistent radiation patterns. The antenna allows a frequency-unlimited high-efficiency operation of a dual-channel multiplier-chain based power source module with a peak radiated power of 4.06 dBm at 243 GHz and in excess of -10 dBm for 221-275 GHz.
