“…It is also true that with off-chip components, placed above the chip, the antenna gain could be improved, even significantly. Examples include using lenses [37], placing dielectric resonators [38], [39], or superstrate [7] on top of the chip and feeding those with an on-chip launcher. Although the performance (efficiency and bandwidth) of these hybrid solutions are, in general, better than that of fully on-chip antennas, these techniques require additional processes, which may increase the cost and design complexity.…”

Abstract-A novel fully on-chip antenna based on a metasurface fabricated in a 180-nm BiCMOS process is presented. Inspired by the concept of high impedance surface (HIS), this metasurface is not used as a reflector below an antenna as commonly done. Instead, it is used as a radiator by itself. The extremely thin metasurface is composed of a patterned top two metal layers and the ground plane placed in the lowest metal layer in the process. The ground plane on the lowest metal layer of the process provides a solid shielding from the substrate and other possible circuitries. The fundamental of the antenna radiation and design are described. The measured antenna shows 2.5 dBi peak broadside gain with 8-GHz 3-dB gain bandwidth and an impedance bandwidth larger than 10 GHz. In its class of broadside radiating fully on-chip antennas, with a ground plane on the lower metal layer of the process, and without additional fabrication processing, this structure achieves the widest impedance bandwidth at W-band and one of the highest gain and gain bandwidth. It is noteworthy that this is achieved with an extremely thin antenna substrate thickness and a shielding ground plane.Index Terms-Artificial magnetic conductor, high-impedance surface, leaky wave antenna, Marchand balun, millimeter wave, millimeter wave antennas, on-chip antenna.

Abstract-Day after day, recent advances in millimeter wave communications have called for the development of compact and efficient antennas. Furthermore, the greatest challenges in this area is to get a good performance and a miniaturized antenna. In addition, the design of antenna, in the Silicon technology, is one of the key challenges. In this way, this work will focus on the design of the free 60 GHz band, high gain and high efficiency onchip antenna meandering slots for transponder Radio Frequency Identification (RFID). Further, the stacked dielectric resonators (DRS) will be arranged above the power element of on-chip antenna with an excitation of coplanar waveguide (CPW). We will use the Scattering Bond-Graph formalism like a new technique to design these proposed antennas and we will use the microwave Studio CST software simulation to validate the results. We have miniaturized the proposed antenna after having such a number of iteration and by applying the Bond Graph methodology, and the size of the antenna is about 1.2 * 1.1 mm 2 .

“…The second category of DRAs uses either silicon [15][16][17][18] or GaAs [7] substrate that can carry the driving electronics. In [15,16], a DRA was fed by a coplanar waveguide (CPW) to excite the HE 11δ mode.…”

“…However, it suffered from low radiation efficiency (51%). In [17], the DRA was fed by a H-slot which excited the TE 11δ mode. This antenna has an improved radiation efficiency of 59% while its measured gain was 0.…”
