It is an tenna design using microstrip patch for GPS application (review).-It is an antenna design using microstrip patch for GPS application (review).

A patch antenna (also known as a rectangular microstrip antenna) is a type of radio antenna with a low profile, which can be mounted on a flat surface.

在设计microstrip patch antenna:输入中心频率、介质基板厚度和介电常数，得到 patch的设计参数和馈电位置(In the design microstrip patch antenna: input center frequency, dielectric substrate thickness and dielectric constant, get patch design parameters and feed position)
