Abstract
A compact dual narrow band microstrip antenna particularly suited for remote wireless metering includes a dielectric, a directly fed radiating element, a parasitic radiating element gap coupled to the directly fed radiating element and a truncated ground plane. Each radiating element is partially shorted to the ground plane and each radiating element has a reactance window to lengthen the current path. The reactance window and partial shorting reduce the size of the each radiating element. The antenna is compact with good isotropic characteristics and sensitivity to two perpendicular polarizations.
