Along with explosive spread mobile phone, wireless LAN, and such as satellite broadcasting, the rapid development of broadband, the need for high-speed wireless data communication is growing rapidly. Asa problem in the wireless communication device, it is difficult to realize miniaturization of the passive device such as antenna and bandpass filter. Moreover, it is difficult to fabricate miniaturized on-chip impedance matching circuit. In order to solve these problems, miniaturized antenna and CMOS RF front-end chip with impedance matching circuit were designed and fabricated, and tested.

除了爆炸性传播手机，无线LAN以及诸如卫星广播，宽带的快速发展之类的诸如高速无线数据通信的需求正在迅速增长。无线通信设备中的ASA问题，很难实现被动装置（例如天线和带通滤波器）的微型化。此外，很难制造微型片上阻抗匹配电路。为了解决这些问题，设计和制造并进行了测试，设计和制造了带有阻抗匹配电路的微型天线和CMOS RF前端芯片。
