Abstract
In recent years there has been an increasing focus on the technology of commercial products associated with the development of wireless sensor network. In the near future, we believe that wireless sensor network will be all around and incorporated into our daily life. But we find a problem with the antenna design of wireless sensor. The antenna suffers from the influence of metal environments, such as the battery. And we can’t abate the interference because of the limited space available in the sensor node. In this article, we use the standard suggested by IEEE 802.15.4 to decide the gain and frequency required for different indoor environment. We chose antennas suitable for the metal environment at the same time. In this thesis, we propose a patch type antenna with a shorting wall and a parasitic antenna. The shorting wall is to reduce the size of patch. The parasitic antenna is to increase the bandwidth. We also prepared an experiment to test the printed inverted F antenna and this work in the metal environment. The experimental results show that our antenna is less sensitive to the metal environment.
