Abstract
A bowtie slot on-chip antenna (OCA), exhibiting multiband operation at 94 and 140 GHz is presented. The first of its kind on-chip multiband operation is achieved by adding parasitic loading elements in the slots. The bond-pads along with a shunt-stub, form the impedance matching network of the antenna. Designed in IHP 130nm BiCMOS process, the simulated gain of the proposed antenna is -4.09dBi and -4.76 dBi at 94 GHz and 140 GHz respectively while occupying 494 x 366 x 650 mu m(3). The small on-chip dimensions at mm-wave frequencies along with the presented multiband operation can be extremely useful for supporting multiple upcoming wireless communication applications.
