Microstrip antenna technology has been the most increasingly developing topic in antenna field in the last twenty years. This manuscript presents a new combined double A-shaped miniaturized microstrip patch antenna (MPA) is presented and proposed which satisfies almost full bandwidth requirement of X-band authorized by IEEE. The proposed antenna is excited by a matching 50Ω microstrip feedline. The antenna structure is designed and simulated utilizing high frequency electromagnetic simulator tool. The antenna has a structure of 18×20 mm2 and the dimension of the patch is 12×14.6 mm2 which is etched on low cost FR4 dielectric substrate. The overall size is 18×20 mm2 with 1.67 mm thickness. Simulated results showed that, the antenna resonates at frequency of 8.436 GHz and 11.32 GHz which has a return loss of -21.62 dB and -17.92 dB, respectively. The antenna has average radiation efficiency of 65%. The antenna is small in size and has operating bandwidth of 7.984 GHz - 11.78 GHz which covers all applications of X-band microwave frequency. Lower cost, light weight nature and compactness of this proposed antenna is a compatible one to fabricate and suitable for X-band applications like - military, earth to satellite, satellite to earth, weather forecasting etc.
