| Summary: | SCHOTT D263T glass substrate is investigated for millimeter-wave (mm-wave) antenna-in-package applications using integrated passive device (IPD) technology. For comparison, the ring-resonator method and transmission-line method are used to extract the dielectric constant (<inline-formula> <tex-math notation="LaTeX">$\varepsilon \text{r}$ </tex-math></inline-formula>) of the glass substrate up to 67 GHz. The extracted results show good correlation between the two methods. Compared with the ring-resonator method, the transmission-line method requires higher measurement and simulation accuracies as the frequency decreases. Based on the extracted substrate data, a miniaturized Yagi-Uda dipole antenna operating at 60 GHz is designed, fabricated and measured. The measured results show that the antenna achieves a fractional impedance bandwidth (<inline-formula> <tex-math notation="LaTeX">$|S11| < -10$ </tex-math></inline-formula> dB) of 57.1% (<italic>i.e</italic>. 36.4 to 65.5 GHz), and stable gains of 5.5± 0.5 dBi from 40 to 67 GHz with the dimension of <inline-formula> <tex-math notation="LaTeX">$3.4\times 4$ </tex-math></inline-formula> mm<sup>2</sup>. The simulated radiation efficiency is >90% from 45 to 67 GHz, and the measured results agree well with the simulations. |
