Abstract
A multibending antenna structure includes a substrate, a grounding layer, and a microstrip antenna layer. The ground layer and the microstrip antenna layer are disposed on two sides of the substrate. The microstrip antenna layer includes a radiation unit which is in a multibending shape and formed with a concave area. The length of the radiation unit is equal to 0.8 to 1.2 time the wavelength corresponding to an operation frequency. When the input end of the radiation unit receives a signal input to emit an electromagnetic wave having a radiation energy, the half-power beam width thereof is increased.
