Abstract

Multiband microstrip antennas are significantly popular due to their ease of fabrication, thin profile, conformal and adaptability to dual and triple band applications. The impedance matching, polarization purity, low spurious radiation with optimum gain condition between the line and patch depend on the type of feeding technique used. The present paper describes the design and simulation of Multiband microstrip patch antennas with different feeding techniques and analyzed using Finite Element Analysis Method based HFSS (High Frequency Structure simulator) software. A new compact multiband planar CPW fed Microstrip antenna is proposed in this work. The performance of the proposed multiband antenna is analyzed, and compared with edge and coaxial feeding techniques in terms of different radiation characteristics including Return loss, Gain, VSWR, Front-to-Back Ratio etc.
