A dual-notch loaded microstrip antenna has a single-medium substrate, a metal layer and a microstrip antenna layer, wherein the microstrip antenna layer of the microstrip antenna is etched into a double dual-notch or a single dual-notch structure. The microstrip antenna layer and the metal layer adhere respectively to opposite sides of the single-layer substrate, wherein the metal layer works as the electrical ground. The single-layer substrate contains a penetrating opening whose diameter and location are predetermined. The task of transmitting and receiving dual-band or multi-band signals is carried out by feeding the microstrip layer with signals from a connector, such as a coaxial connector, through the penetrating opening.
