Polarization This article presents a multi-band right-hand circularly polarized antenna designed for the Cube Satellite (CubeSat). 17λ 0 × 0. Whether you’re operating on 2 meters or you work in the 1. In this paper, we describe the design and fabrication of an antenna with circular polarization for an RFID reader in the UHF band. Linear polarization and circular polarization are two different ways in which radio frequency (RF) energy can be transmitted from an RFID antenna. Understanding the differences between these two types of polarization is crucial for optimizing the performance of an RFID system. References [1] Marrocco G.
