PURPOSE: An electromagnetic coupling printed slot micro-strip antenna is provided to obtain broader band high gain characteristic with a small plane structure and accomplish mass production. CONSTITUTION: An electromagnetic coupling printed slot micro-strip antenna comprises a radiating element(21), a feeding line(24) and a ground plane(22). The radiating element(21) is a rectangular metal sheet having a meander line slot for transmitting/receiving a signal. The feeding line(24) is arranged under the radiating element(21) and crossed perpendicularly with the starting point of the radiating element(21) for feeding an electrical signal. The ground plane(22) is formed on the other area than the slot of the radiating element(21). By varying the width and the length of the slot, operating frequency band is readily adjusted with the antenna. By changing the position of the feeding line(24), characteristics such as standing wave ratio, radiating pattern and gain of the antenna are improved.
