In this letter, the aptness of the combination of three-dimensional (3-D) printing and radio frequency identification (RFID) is faced by presenting a compact, low-profile, and cost-effective circularly polarized antenna for handheld UHF RFID reader. The radiating element has been realized through a circular array of four inverted-F monopoles, where the array elements are excited with a 90 degrees phase offset through a microstrip feeding network, realized in 3-D printing technology as well. Taking advantage from low losses and moldability of the 3-D printing materials joint to a specific design strategy, the proposed antenna realizes an improved gain and an appreciable size reduction if compared with the state of the art.

Abstract

In this letter, the aptness of the combination of three-dimensional (3-D) printing and radio frequency identification (RFID) is faced by presenting a compact, low-profile, and cost-effective circularly polarized antenna for handheld UHF RFID reader. The radiating element has been realized through a circular array of four inverted-F monopoles, where the array elements are excited with a 90 degrees phase offset through a microstrip feeding network, realized in 3-D printing technology as well. Taking advantage from low losses and moldability of the 3-D printing materials joint to a specific design strategy, the proposed antenna realizes an improved gain and an appreciable size reduction if compared with the state of the art.
