A new type of a compact tag antenna, which can be effectively mounted on metallic platforms, is proposed for UHF band RFID systems. The proposed antenna consists of a simple microstrip path and feed line, and it is fabricated on a very thin (4 mm) subtrate compared with previous works. The proposed antenna can be easily matched to the microchip by using the inset feed line and short stub. Slits are inserted to adjust the resonant frequency of the radiating patch. The antenna is analayzed by simulations by Ansoft HFSS software, and the measured results based on backscattering method are provided.

The Port treat 99.7% of freight for imports & exports in our country. So The Port is much accounted of the economy. Then the government and economy study about rasing port efficiency and productivity. But most of the studies are related with container terminal. Container is easy to treat. Because container is standardized. And it also is easy to implement to a system. But general terminal which treats bulk-cargo or general cargo is not. In this study, Stevedoring System applying PDA is developed by analyzing current system and business process. It is based on Web Service. So It is easy of access.
