Antenna array integrated on multilayer organic package for millimeter-wave applications

A high-directivity microstrip-fed Yagi-Uda antenna has been developed for millimeter-wave applications. This work proposed antenna is built on a low-cost and low-loss multilayer organic substrate for flip chip ball grid array (FCBGA) package. The proposed antenna achieves both broadband and high gain characteristics, which meets the requirement of IEEE 802.11ad standard. The four-element Yagi-Uda array is also implemented to low-cost and low-loss multilayer organic substrate. The four-element design results in a peak gain of 12 - 14.5 dBi at operating frequency band. The proposed antenna shows excellent performance in free space and is suitable for millimeter-wave application, such as smart phone, laptops, and wireless router for point-to-point communication systems.
