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.

A novel compact quad-band planar antenna using meander-line, multi-stubs, and slots for WiMAX, WLAN, LTE/5G sub-6 GHz applications

“…Two-antenna pairs are arranged vertically on two sides of the ground plane to produce dual bands of 3.4-3.6 and 4.8-5 GHz. Although many of the reported antennas accomplished wide/multiple operating bands [21][22][23], their 3D profile has a complicated geometry, making it hard to realize. Furthermore, some of the suggested designs partially cover the sub-6 GHz band.…”
