Wideband dipole antenna using multiple‐mode resonator for long‐term evolution application

Abstract

A coplanar waveguide fed wideband dipole antenna using a multiplemode resonator is proposed and developed. A simple dipole antenna structure is investigated for its wideband radiation performance by virtue of its single, double, triple and quadruplet resonant modes. Later, a metallic reflector is properly installed in order to provide a unidirectional radiation pattern as demanded for the long-term evolution (LTE) application. In the design, a quadruplet-mode wideband dipole antenna is explored to cover the LTE operation band with a 10 dB fractional bandwidth of 46.8%. Finally, an antenna prototype is fabricated and tested to experimentally verify the expected wideband property and predicted results.

Wideband and compact horizontally polarized omnidirectional antenna using composite dipole elements

“…If another parallel resonance can be utilized and got close to the original parallel resonance, a wideband property will be obtained. This method has been proved in literatures …”

“…This method has been proved in literatures. [12][13][14] The PSL also can make this effect. By using parallel strip line with quarter-wavelength, the proposed antenna in Ref.…”
