Abstract :
A compact broadband balun on a silicon substrate is proposed for millimeter-wave applications. By utilizing a novel defected ground structure, it is expected that the balun exhibits an amplitude balance less than 0.5 dB and a phase balance less than 2 degrees in a frequency range from 26 GHz to 80 GHz. The insertion loss is less than 3 dB in the operational frequency band. The balun achieves a bandwidth of 108 % and the area occupies only 0.024 mm2.
