Abstract

This work presents the use of a three-element radiating structure for circularly polarizedLow-Power Wide Area Network (LP-WAN) communication with space. The proposed structure hasa 72 mm×72 mm×12 mm compact size with Right-Handed Circular Polarization (RHCP) and a120◦wide beamwidth radiation pattern. Printed on low-cost FR4 Epoxy substrate, a feeding networkcircuit based on Quasi Lumped Quadrature Coupler (QLQC), it achieves a−0.6 dB insertion loss anda very compact size. The final structure has a 69% total efficiency and a 3.14 dBic realized gain.
