Wideband Circularly Polarized 3D Wire Antenna for Wi-MAX Applications

Abstract : In this paper, a crooked wire antenna is optimized to be functional in both the WLAN and the Wi-Max bands (2.4-2.48 and 3.3-3.7 GHz). The antenna presents a right-hand circular polarization (RHCP) with a 3 dB axial ratio (AR) bandwidth of 3.28 to 4.11 GHz. For the WLAN band (2.4-2.48 GHz), the polarization was linear. The antenna is fabricated using 3D printing techniques and occupy a total volume of 33.8 mm × 30.4 mm × 37.4 mm. The simulated and measured farfield results show good agreement with a radiation pattern that assures a near hemispherical coverage toward the upper hemisphere and a measured maximum gain value of approximately 6 dB. The radiation pattern of the antenna assures a near hemispherical coverage toward the upper hemisphere.
