A broadband dual-polarized planar antenna element for mobile communication base station is presented in this paper. It is formed by two crossed modified dipoles printed on a substrate and supported upon a reflector by four nylon posts. Simulated and measured bandwidth with VSWR<1.4 are 49% (1.68-2.77 GHz) and 57% (1.63-2.93 GHz), respectively, within which the polarized isolation is better than...
This article presents the design of a wideband slot antenna for LTE indoor distribution system with simply shaped radiator element and wide-slot ground plane. By adjusting the slot's shape and modifying the surface current path and changing the electric field distribution inside the slot consequently, the antenna can operate in wideband and show compact structure. The relative bandwidth of the proposed...
This paper presents a broadside-coupled feeding planar multiband antenna for tri-networks convergence. The antenna consists of a coupled loop and two branch lines. The coupled loop includes a monopole and a coupled shorting line. The proposed antenna forms two wide frequency bands, which is 694∼960 MHz and 1710∼2590 MHz respectively. The measured return loss shows good agreement with simulation.
A reconfigurable antenna with two beams is designed and characterized as the polarization and angle diversity for wireless communication applications. It has built-in quadri-polarization and has different pointing direction as the function of frequency and polarization mode. The antenna is proposed at 35 GHz and implemented based on the substrate integrated waveguide (SIW) technology. All circuits...
