A two-dimensional antenna array has n rows of 1×m one-dimensional array and each one-dimensional array is composed of multiple single differential feeding antennas. Each single differential feeding antenna has a differential feeding structure and a microstrip antenna stripe. A length of the microstrip antenna stripe is no longer than a dielectric wavelength so the microstrip antenna stripe is not excited to a high-order mode. An angle of inclination of a main beam aligns with the broadside and a width of the main beam is further concentrated at elevation direction. The differential feeding structure can reduce an even mode to enhance an isolation. The one and two-dimensional antenna array is miniature by using the small single differential feeding antennas. In addition, the isolation and gain of a dual-antenna system using the two-dimensional antenna arrays or the one-dimensional antenna arrays are further enhanced and increased if more feeding antenna arrays are used.
