TL;DR: In this paper, a hybrid plasmonic nano-antenna is presented, which has metal insulator metal (HMIM) multilayer configuration and has an overall size of 1.7 × 1.175 μm.
Abstract: This paper presents a novel hybrid plasmonic nano-antenna. It has metal insulator metal (HMIM) multilayer configuration and has an overall size of 1.7 × 1.175 μm 2 to resonate at 1.55 μm wavelength. The proposed antenna is fed by an HMIM plasmonic waveguide to achieve good impedance matching. Simulation results show that the proposed plasmonic nano patch antenna emits a broadside radiation pattern with a bandwidth of 0.282 μm (1.471–1.753 μm). The achieved antenna gain and efficiency are 4.5 dB, and 60%, respectively. The proposed antenna is practically realizable and can be fabricated using standard semiconductor fabrication process. Moreover, it could be used for numerous chip-scale applications such as wireless interconnects energy harvesting, photoemission, photodetection, scattering, heat transfer, spectroscopy, and optical sensing.

TL;DR: This paper introduces a chipless Radio Frequency Identification tag to be used for oil and gas pipelines monitoring applications that uses multiple E-shaped resonators to introduce multiple notches in the operation band, giving any required number of bits in the spectrum signature.
Abstract: This paper introduces a chipless Radio Frequency Identification tag to be used for oil and gas pipelines monitoring applications. The proposed tag uses multiple E-shaped resonators to introduce multiple notches in the operation band, giving any required number of bits in the spectrum signature. Two cross-polarized semi-circular patches with partial grounds are used as the tag antennas. The proof of the concept is done using vector network analyzer measurements with two implemented Vivaldi antennas as transmitter (Tx) and receiver (Rx). The experimental data match will with the expected results.
