This paper presents a high-gain on-chip antenna implemented in standard Si technology for millimeter-wave applications. A cubic dielectric resonator is mounted upon a \'microstrip\' form circular patch antenna. Different from other works, a very thin SiO2 layer which is of about 4 m thick is used, and the whole structure is rather simple, which means that it can be easily fabricated and scaled. The fabricated antenna occupies a size of 1.45 mm*0.9 mm. The simulation results indicate that the gain at 95 GHz and 99.4 GHz are 4.0 dBi and 4.6 dBi, respectively. And the peak efficiency and radiation efficiency of the proposed antenna reaches 62% and 72%. While the antenna efficiency and realized gain from 92.5 GHz to 95.8 GHz and from 98.7 GHz to 100.1 GHz for side-fire radiation are above 35% and 0 dBi.

This paper presents a miniature and high gain on-chip V band microstrip antenna. A ground plane on the bottom metal layer M-1 has been approached to shield the wave from penetrating into the low-resistivity and high dielectric constant Si substrates to improve the antenna performance. Antenna parameters have been investigated to obtain an optimized antenna with 0.87 mm * 1.16 mm occupation. The measured and simulated return loss results and simulated radiation pattern results of proposed antenna have been presented. The performance of the proposed antenna as compared to other published on-chip antennas has also been demonstrated.
