A cost-effective antenna package suitable for mass production mm-wave applications is investigated. Different packaging material that can be possibly used in mm-wave antennas are presented and compared. Moreover, this study investigates different methods of packaging millimetre-wave (60 GHz) MEMS antennas. The paper first introduces the custom needs for optimum operation of the MEMS antenna and then...
Two new MEMS antennas operating at 77 GHz are presented in this paper. The first antenna is linearly polarized. It possesses a vertical silicon wall that carries a dipole on top of it. The wall is located on top of silicon substrate covered with a ground plane. The other side of the substrate carries a microstrip feeding network in the form of “U-turn” that causes 180° phase shift. This phase-shifter...
Two novel MEMS antennas for 60 GHz applications are introduced in this paper. The first antenna is radiating linearly polarized wave, while circularly polarized wave can be radiated from the second antenna. Both antennas possess good isolation from the driving circuit via the presence of ground metal plane. The fabrication process requires only one silicon wafer with no need for wafer bonding or hybrid...
A novel MEMS antenna is introduced in this paper. This antenna is capable of operating at both 60 GHz and 77 GHz. The proposed antenna enjoys good isolation from the driving circuit, low fabrication cost, and high mechanical stability. These features are achieved together via a new fabrication technology that allows the realization of MEMS antennas with ground plane isolation from the driving circuits...
In this paper, a novel MEMS antenna array is presented. It can be fabricated on a single silicon wafer without any need for wafer bonding or hybrid integration. The proposed array is of the wire-grid type, namely a "brick-wall" structure. Such array can be built by connecting a number of radiating wires via a number of connectors. Unlike the regular arraying technique, the radiating elements...
