Abstract
To meet the growing demand for miniaturization and compactness, antennas are being designed over CMOS chips. On-chip antennas (OCAs) suffer from low gains and radiation efficiency due to high dielectric constant and low resistivity of Silicon. Artificial magnetic conductors (AMC) are used in OCAs to increase gain and reduce power confinement in the substrate. In this paper, a bowtie slot antenna is presented whose gain is enhanced by an array of back-to-back E-shaped (B2BE) frequency selective surface (FSS). The operating frequency of antenna is 94 GHz where its gain is boosted from -2.71 dBi to -1.94 dBi. Designed in a standard IHP 130nm BiCMOS process without any extra post-processing step, the S11 is below -10dB from 90 GHz to 105 GHz with an antenna size of 710 x 310 x 650 mu m(3).
