Integrated wideband dipole antenna for pulse beam-formability by using 0.18-µm CMOS technology

A wideband on-chip dipole antenna for fully integrated pulse beam-forming purpose has been designed and fabricated. The antenna element in meandering shape is located in the top metal of a 1.8-V 5-metal-layer 0.18-μm CMOS chip. The antenna´s bandwidth from S-parameter measurement is 4.4 GHz with operating frequency range from 7.4 GHz to 11.8 GHz. A CMOS integrated pulse generator with possibility of pulse delay adjustment is included to the antenna´s terminals. The minimum delay resolution is 2.3 ps in post-layout simulation. The 1.1-mV peak-peak (p-p) received pulse voltage at 10-GHz resonant frequency is achieved by using a 20-dB standard horn antenna with 38-mm distance to the chip.
