Claim:
1. An active antenna module, comprising: a substrate comprising a first surface and a second surface opposite to the first surface; a first microstrip antenna metal sheet disposed on the first surface of the substrate; a second microstrip antenna metal sheet disposed on the first surface of the substrate; a third microstrip antenna metal sheet disposed on the first surface of the substrate; a first coupling metal sheet disposed on the second surface; a second coupling metal sheet disposed on the second surface; a third coupling metal sheet disposed on the second surface; and a radio frequency transistor disposed on the first surface, the radio frequency transistor comprising a control port, a first port, and a second port, the control port being connected to the third microstrip antenna metal sheet, and the first port and the second port being respectively connected to the first coupling metal sheet and the first microstrip antenna metal sheet; wherein a first portion of the first microstrip antenna metal sheet and the first coupling metal sheet form an equivalent bypass capacitor, a second portion of the first microstrip antenna metal sheet, a first portion of the second microstrip antenna metal sheet adjacent to the second portion of the first microstrip antenna metal sheet, and the second coupling metal sheet form a first equivalent coupling capacitor, a second portion of the second microstrip antenna metal sheet, and portions of the third microstrip antenna metal sheet adjacent to the second portion of the second microstrip antenna metal sheet, and the third coupling metal sheet form a second equivalent coupling capacitor.
