Low‐cost, compact millimeter‐wave antenna‐in‐package for short‐range wireless communications

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 × 5.5 mm × 0.13 mm and 6 mm × 7.2 mm × 0.13 mm, respectively. The antenna has measured beamwidths of 68° (E‐plane) and 105° (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 . © 2016 Wiley Periodicals, Inc.
