Microstrip antenna

The utility model discloses a microstrip antenna. The microstrip antenna comprises a first insulating substrate, a second insulating substrate, a conducting layer, a plurality of conductive strips and a feeder; the conductive strips are parallelly arranged on the upper surface of the first insulating substrate; the conducting layer is clamped between the first insulating substrate and the second insulating substrate; an aperture is formed on the conducting layer and is overlapped with the conductive strips; and the feeder is arranged on the lower surface of the second insulating substrate and overlapped with the aperture. According to the utility model, the characteristic of strong directional property of an aperture-coupled antenna array is utilized, so that the capability that the antenna receives wireless signals from the sky is improved, and the capability that the antenna receives wireless signals reflected by the ground is weakened at the same time; besides, due to the function that the antenna is integ
