This communication reports a ceramic antenna for tri-band radio devices operating in the 2.4, 5.2 and 60 GHz bands in low temperature cofired ceramic technology. It integrates a microstrip grid array antenna for the 60-GHz band, a meander-line monopole for the 5.2-GHz band, and a helix monopole for the 2.4-GHz band in a substrate of size 15×15×0.48 mm3. Both simulated and measured results are presented and discussed.
