Design and Characteristics Investigation of Multiband Microstrip Patch Antenna for Wireless Application
In this paper, the authors present design and characteristics investigation of a low-profile compact micro-strip patch antenna for multiband application. The antenna with a novel structure is designed on FR4 substrate having dielectric constant 4.4. The proposed antenna consists of a patch with four narrow slits and ground plane to generate six bands of frequency at 1.34, 1.99, 2.98, 3.27, 3.56 and 3.86GHz for different wireless systems. The design is simulated using an soft HFSS software. For verification of simulation results a prototype antenna is fabricated and tested. Both simulated and measured results are shown to illustrate the performance of the proposed antenna design.
