Monolithic Reconfigurable Patch Antenna and Antenna Arrays in V-band

This paper presents a monolithic reconfigurable antenna and antenna arrays for V-band applications. They are designed on a silicon substrate in a monolithic manufacture with distributed highly doped areas integrated in the substrate as active elements. Designing a V-band antenna with integrated active elements for tunability offers several key advantages reducing the interconnections problems, improving the antenna efficiency, and pushing over the frequency limitation with classical active components. Moreover, the proposed co-design method offers some degrees of freedom in the positioning and the shape of the doped areas improving the antenna efficiency. To demonstrate the approach, a reconfigurable V-band antenna is proposed. In the ON-state, it resonates at 60 GHz and in the OFF-state, the frequency can be chosen between 62 GHz to 74 GHz thanks to the degrees of freedom of the proposed approach. To go further, a 1x2 and a 1x4 frequency reconfigurable antenna arrays are discussed.
