Design and Development of Integrated Patch Microstrip Antenna for Wideband Operation

A novel geometry of integrated truncated coupled monopole microstrip antenna (ITCMMA) has been designed for the resonant frequency of 3.5 GHz. The rectangular and triangular patches are designed for the same resonant frequency. The triangular patch is placed along the radiating edge gap coupled to the rectangular patch in order to make the antenna resonate repetitively for wide bandwidth. The truncation is made along the edge of the patch for compactization. Microstrip line feed is used to excite the antenna. The monopole technique is used in the construction of proposed antenna. The antenna gives a bandwidth of 110.8% with a gain of 8.69dB. The radiation patterns are omni directional in both E and H plane. The simulation and experimental results of return loss is in good agreement with each other. The antenna may be useful for WLAN microwave communication applications
