Design of on-package microstrip antennas for single-chip wireless transceivers

The recent advances in single-chip solutions of wireless transceivers have called for the parallel development of compact and efficient antennas. This paper addresses the design of on-package microstrip, antennas for single-chip wireless transceivers. A microstrip antenna realized in the format of an integrated circuit ceramic ball grid array (CBGA) package measures only 15×15×1.9 mm. Results show that the on-package microstrip antenna achieved impedance bandwidth of 1% and radiation efficiency of 80%, and gain of 2 dBi at 5.6 GHz. Details of design and analysis of this on-package microstrip antenna are presented and discussed.
