Radiation characteristics of ultra-small wireless communication modules for 60GHz band WPAN

A planar dipole antenna was designed for 10mm square 60 GHz band ultra-small and low-cost modules using any layer interstitial via hole (ALIVH) substrate. The planar dipole antenna was patterned on the top layer of the module. Simulated results showed that bandwidth and gain of the proposed module were sufficient for 60 GHz wireless personal area network (WPAN) system. We fabricated the proposed module with a planar dipole antenna. Maximum actual gain of the fabricated module of 6.0 dBi at 63 GHz was measured. Proposed antenna patterned on ALIVH substrate for 60 GHz band module has enough potential for being used as a compact antenna for 60 GHz band WPAN modules.
