Antenna integration for SiP systems

Abstract

New data communication applications are creating large numbers of new wireless devices with continuously more stringent requirements: smaller size, weight, higher frequencies and bandwidth and lower power consumption at an ever-decreasing cost. True RF systems-on-a-chip (SoC) remain however very difficult to realise since many passive components and particularly the antenna cannot be integrated in a cost effective way with sufficient quality or size on the same Si-die. Therefore, a systems-in-a-package (SiP) approach is required. In this overview paper several technology choices of integrated antennas for wireless systems ranging from microwave to mm-wave frequencies are discussed through integration examples of various wireless modules.
