Design of Antenna-in-Package in 5G Communication Band Based on LTCC Technology

Antenna-in-Package(AiP) technology has an advantage that a system can maintain antenna performance while being small in size and highly integrated. In this paper, based on LTCC technology, a rectangular corner cut microstrip antenna for 5G communication band is designed, and then integrated into a package of the chip with AiP technology. The simulation results of HFSS software show that after miniaturized and highly integrated, the AiP system achieves the goal with operation frequency of 4.8 ~ 4.9GHz, bandwidth of 100MHz and the peak gain of 6.52dB.
