A 60-GHz Integrated Slot Loop Antenna in 0.13-µm BiCMOS Technology

This paper presents a rectangular slot loop antenna integrated in a standard 0.13-μm BiCMOS technology. By using the slot loop antenna, it can easily satisfy the metal density rules without dummy metal fill and can be integrated with other circuitry. The total area of the antenna including the ground plane is 0.883 mm² and the loop antenna only occupies 0.24 mm². The antenna resonates at 59.93 GHz and the bandwidth is 5.44 GHz from 57.82 GHz to 63.26 GHz. The simulated total gain is 2.69 dBi while the efficiency at 60GHz is 86%. The radiation efficiency is better than 74% over the band.
