A single-layer patch antenna, which is constructed using two complementarily placed C-
shaped patches, has been proposed for designing a metal-mountable tag with a wide range …

A folded patch, which is centrally fed by a coplanar feedline, is proposed for designing a
miniature UHF tag antenna for mounting on metal surfaces. The tag is designed using a …

For the first time, a planar and low-profile magnetic loop antenna is proposed for designing
an omnidirectional metalmountable radio frequency identification (RFID) tag antenna. The …

A miniature folded patch with a dimension of 40 mm× 40 mm× 1.6 mm (0.1156 λ× 0.1156 λ×
0.0046 λ at 867 MHz) is proposed for designing a passive metal-mountable tag. It consists of …

We propose a flexible anti-metal radio frequency identification (RFID) tag antenna based on
a high-conductivity graphene assembly film (HCGAF). The HCGAF has a conductivity of …

A compact dipolar patch, which has a dimension of 23 mm× 16 mm× 1.6 mm (0.0702 λ×
0.0488 λ× 0.0049 λ), is designed for mounting on metal. The proposed antenna consists of a …

A semiflexible E-shaped folded patch with a compact footprint of 30 mm× 30 mm x 3 mm
(0.091 λ× 0.091 λ× 0.0091 λ at 912 MHz) is proposed for designing a miniature ultrahigh …

A novel compact 3-D-dipole antenna for a radio frequency identification (RFID) tag is
presented in this article. The proposed antenna enables the tag to be read when mounted …

A new type of tag antenna, which is made by placing four identical planar inverted-L
antennas (PILAs) in rotational symmetry constellation, is proposed for designing a miniature …

A double-layer antenna with a small footprint of 47 mm mm mm is proposed for broadband
on-metal applications. Here, a rectangular loop is deployed to excite the underneath patch …
