Abstract

A broadband linear polarized antenna is designed for radio frequency energy harvesting. The antenna covers the frequency range from 1 up to 6 GHz with relative impedance bandwidth of 126% at −6 dB reflection coefficient |S11| and extended from 1.1 to 3.3 GHz and from 4.2 to 5.6 GHz at |S11| ≤ −10 dB. A 2 × 2 dual linear polarized (DLP) antenna array is designed based on the antenna element by using equal phase and equal power divider 1-to-4 Wilkinson power divider with 180° phase shifter. The DLP antenna array covers the frequency band from 1.8 to 2.9 GHz. This frequency band covers a wide range of modern wireless communication standards, including GSM 1800, UMTS 2100, Wi-Fi 2.4, and most of LTE bands. The developed array prototype was then used to experimentally validate the simulation results. The horizontally and vertically polarized gain of the designed array were found to be quite similar across the 1.8–2.9 frequency band with an average gain value of 5.5 dBi.
