Embedded 5G Wideband Dual-Polarized mm-Wave Antennas in Non-mm-Wave Antennas Integrating a Package (AiAiP) for a Metal-Framed Cell Phone

4 embedded wideband dual-polarized mm-Wave antennas as a linear array in a non-mm-Wave antenna integrating a package (AiAiP) for the $5^{\mathrm{t}\mathrm{h}}$ generation mobile communications (5G) cell phone with a metal frame which also functions as a long-term evolution (LTE) antenna and with a high display active-area (A.A.)-to-body ratio beyond 91.7% is presented. For the simulated reflection coefficients $|\mathrm{S}_{\mathrm{n}\mathrm{n}}|\leq -10\mathrm{d}\mathrm{B}$, the bandwidths of the 5G mm-Wave antenna array for the dual polarizations (pol.) at $\varphi=45^{\circ}$ and $\varphi=-45^{\circ}$ range from 24.19 GHz to 29.54 GHz and from 35.90 GHz to 40.24 GHz. All current 5G licensed mm-Wave bands n25S, n257, n261, and n260 in the third generation partnership project (3GPP) can thus be covered. The bandwidths of $|\mathrm{S}_{\mathrm{n}\mathrm{n}}|\leq -6\mathrm{d}\mathrm{B}$ for the LTE antenna range from 878 MHz to 971 MHz and from 2258 MHz to 2763 MHz, so the LTE Band 8 (880-960 MHz), Band 40 (2300-2400 MHz), and Band 41 (2496-2690 MHz) can be supported with the antenna efficiencies higher than –3.03dB in the Band 8 and higher than –1.30dB in the Bands 40 and 41.
