Millimeter-Wave 5G Antenna-In-Package for Mobile Devices Featuring Intelligent Frequency Correction Using Distributed Surface Mount Technologies

A new class of frequency adaptive 5G front-end architecture incorporating three function blocks is proposed, analyzed, and verified using surface-mount technology (SMT) for a millimeter-wave (mmWave) 5G mobile devices. At high frequencies, such as mmWave spectrum, antenna systems often times suffer from unexpected interference by internal or external factors. Therefore, a tunable matching network (TMN) topology is proposed using active components (multi-throw switching chip), which is applicable to feedline of antenna featuring any arbitrary input impedance. The distributed SMT is exploited for compatibility with the current mmWave phased array 5G architectures. The measured results demonstrate that the fabricated 5G AiP can radiate maximum depending on the switch state covering at 27 GHz and 28 GHz, respectively. As a result, the proposed architecture exhibits the peak gain of more than 12 dBi at both states with an output power of 5 dBm/channel.
