This article presents a low-cost, compact millimeter-wave antenna-in-package (AiP) for short-range wireless communications. The antenna is based on a Yagi-Uda antenna for high gain and end-fire radiation and is implemented on a single dielectric layer using a truncated printed circuit board. Integrated with a CMOS transceiver chip, the AiP provides a low-cost, compact, and robust design. The antenna comprises a microstrip-to-coplanar strip line transition, driver, reflector, and director. The fabricated antenna and AiP have dimensions of 6 mm X 5.5 mm X 0.13 mm and 6 mm X 7.2 mm X 0.13 mm, respectively. The antenna has measured beamwidths of 68 degrees (E-plane) and 105 degrees (H-plane) and a gain of 6.6 dBi at 60 GHz, while the fabricated AiP achieved a 10.7-Gb/s wireless data transmission rate over 5 cm at a bit-error rate of less than 10(-12).
