Chip multilayer antenna for 2.45 GHz-band application using LTCC technology

Utilizing the radiation from not only the antenna but GND plane of antenna-mounted terminals can contribute to reduce the size and weight of a chip antenna drastically without spoiling high performance. The optimization of the mounting conditions for the chip multilayer antenna is indispensable to realize higher performances. A wide bandwidth of more than 100 MHz (VSWR<2) is required for the 2.45 GHz applications such as Bluetooth, Home-RF and so on. This paper investigates optimization of the mounting conditions for the chip antenna. The chip multilayer antenna is a suitable antenna for 2.45 GHz-band applications under the optimized mounting conditions.
