ABSTRACT
The wireless network products are getting mature, thus a standard regulation has been set up for producer. Meantime, the relevant technology is steadier then when such products were just developed. The speed problems have also been overcome gradually. The entering threshold has been lowered down; therefore consumers have more purchasing choices. Due to such figures market competition, how to upgrade products’ capacities and to make products more convenient for consumers have become the goals of all leading brands on the market. Under the trend of getting light, thin, short and small, antenna, no matter they are built-in plug-in, or built outdoors for general public or outdoor users, is a topic to be discussed. This article will discuss the application of Microstrip Antenna in Wireless Network Card, and its application in Wireless catch point. The application of Wireless Network System (including 48V Power over Ethernet) , the testing and stimulation in Microstrip Antenna and practical implication in Wireless Network Card, will also be discussed in the product of using all Wireless products of unify and to develop into advantage of a even area.
