A Circularly Polarized Microstrip Antenna with Dual Circular Polarization Using a 90° Hybrid Coupler and Proximity-Coupled Feeding for LTE 43 5G Applications

A Circularly Polarized Microstrip Antenna with Dual Circular Polarization Using a 90° Hybrid Coupler and Proximity-Coupled Feeding for LTE 43 5G Applications

This paper presents a circularly polarized (CP) microstrip antenna with dual circular polarization that is fed using a 3 dB 90° hybrid coupler to ensure dual-CP radiation. The proximity-coupled structure is used as a feeding technique to obtain a larger operational bandwidth that covers the standard...
