In this paper, the authors present the design and implementation of 2x1 microstrip triangular patch antenna array using microstrip line feed for x-band. The design of microstrip patch antenna array is realized using Quarter wavelength transformer. The operating frequency of microstrip patch antenna array is in the range of 8GHz-12GHz is chosen. Each antenna operates in its own operating resonant frequency. The array of two by two microstrip triangular patch antennas with edge feed technique were designed, simulated and measured with the IE3D Zeland software.
