This work presents an ultra-high frequency (UHF) radio frequency identification (RFID) tag
embroidered on a face mask for Internet of Things (IoT) devices. The tag is designed and …

In this paper, a compact and fully passive chipless radio frequency identification planar tag
is proposed based on a modified rectangular resonator. The tag is having a simple design …

In this article, we present the design and validation of an efficient chipless RFID system. A
multi-resonator chipless tag is designed and tested for high bit coding capacity. A high gain …

In this article, a chipless RFID reader antenna based on a modified rectangular‐resonator is
presented. The reader antenna is fabricated and measured to validate multiple narrowband …

Designs of microstrip antenna backed by defected ground plane structure have been
extensively reported for reducing the cross-polar radiation level. However, reported …

This paper presents design and analysis of a beam switchable 1× 2 array patch antenna fed
by a 2× 2 Butler matrix based hybrid coupler for 2.45 GHz radio frequency identification …

This article introduces the design and analysis of a compact, high gain, and wide bandwidth
flower-shaped slotted monopole antenna for RFID reader antenna applications. The …

This article presents a compact meta-surface (MS) based antenna with dual-band operation
for 5G applications. The MS-based antenna consists of a layer of MSs on the top of a single …
