This paper introduces an X-band microstrip patch array antenna that can be suitable for an energy saving system. The presented patch antenna comprises with 2-element linear array. The antenna is simulated using CST MWS and manufactured using FR-4(h=1.0mm, ${\varepsilon}r=4.4$). The estimated bandwidth, gain and beamwidth are 4%(VSWR$\leq$2), 6.3dBi and about 60o in elevation and 15o in azimuth, respectively. The antenna is fabricated and optimized based on the simulation result and installed on the backside of the sensor circuit and measured. The measured bandwidth, gain and beamwidth are 7%(VSWR$\leq$2), 4.8dBi and about 55o(El)/15o(Az), respectively.
