A novel antenna design and packaging solution for tri-band (2.4, 5.2 and 60 GHz) radio application is proposed. The integration of the dual-band monopole antenna and the assembly of the microstrip grid array antenna on a system printed-circuit board (PCB) of practical size are described. A defected ground structure is devised to minimize the impact of the system PCB on the radiation characteristics of the antennas especially in the 5.2-GHz band. Simulated and measured results demonstrate that the novel antenna design achieves excellent performance in the three frequency bands.
