A compact dual-fed circular polarization (CP) antenna array with reflector is designed for radio frequency (RF) energy harvesting system. The antenna composed four patches with dual slots are placed underneath of radiating patches to reduce the antenna's sizes while the reflector is use to reflect the back radiation as well increase the gain. A narrow bandwidth (2.47 GHz – 2.53 GHz) with good axial...
A new configuration of a dual-fed square patch circular polarization (CP) antenna for WiMAX and energy harvesting application is proposed. The normal dual-fed CP is designed at operating frequency of 2.8 GHz and after introducing a slotted ground plane underneath the radiating patch, the operating frequency is reduced to 2.5 GHz while maintaining the patch size and polarization performance. It was...
