Printed Wideband M-Shaped Monopole Antenna for WiMAX Communications

In this manuscript, a printed wideband M-Shaped monopole antenna (PWMM) is proposed for Wi-MAX communications. The design has been simulated using HFSS and mounted on FR-4 substrate (dielectric constant ε
r
= 4.4 and loss tangent= 0.025) of thickness 1.6 mm. A M-Shaped radiator of proposed PWMM antenna with partial ground plane is fed by 50Ω microstrip feed line. A M-Shaped radiator is loaded to achieve WiMAX Communications. The proposed antenna of size 38×36×1.6 mm

achieves a 17% fractional bandwidth in 3.2-3.8 GHz frequency band. The proposed antenna achieves the gain in the excess of 2 dBi with stable radiation pattern. Thus, the proposed PWMM antenna is suitable for Wi-MAX communications.
