Abstract
The invention relates to a microstrip antenna structure positively adding bandwidth, which comprises a dielectric substrate with a radiating metal plate installed on one side and a metal grounding board installed on the other side. The size of the radiating metal plate is smaller than the dielectric substrate and there's a microstrip line extending from edge of one side in proximity of the center position. The microstrip line extends along the edge of the dielectric substrate to be taken as the signal feed line of the microstrip antenna. The invention is characterized by opening a slit on the radiating metal plate, which is close to location over one side in connection with the microstrip and extends along microstrip line direction. Complete the matching structure of the microstrip antenna by virtue of the slit, effectively lowering the inductive effect caused during feeding signal to the microstrip line and increasing the bandwidth.
