Design and Analysis of a Dual-Band Monopole Antenna for RFID applications

Abstract

In this work, a comb-shaped monopole dual-band antenna for 2.4/5.8 GHz RFID application is presented and tested. The proposed antenna is composed of an F-shaped monopole and a three- element comb structure which occupies a compact size of 28 × 32.8 mm 2 including the ground plane. Intermediate structures, including G-shaped, F-shaped, and modified F-shaped monopole radiators , are extensively investigated. To reduce the size of the modified F-shaped structure and cover the 2.4/5.8 GHz RFID operation bands, a comb structure is loaded between the two horizontal arms of the F-shaped branch. By properly selecting the gap , length , width and the
