On the accuracy of estimating input impedance of probe-fed air-substrate microstrip patch antennas using the theory of characteristic modes
Two different techniques based on the theory of characteristic modes are developed to estimate the input impedance of air-substrate, coaxial probe-fed, microstrip patch antennas with arbitrarily shaped patches. Such an antenna with an L-shaped patch is fabricated and experimentally measured, and a …

Design of Miniature Low-Cost Antennas for Compact Low-Data-Rate IoT Terminals
Internet of Things (IoT) is a modern breakthrough technology driving the creation of a hyper-connected, intelligent world, where ubiquitous IoT devices gather and exchange data for monitoring, tracking, and control purposes. It is already being deployed across diverse sectors, such as logistics, …

Analysis and design of planar slot antennas for RFID applications using characteristic mode theory
… are widely used for identification and tracking of objects. The system consists of an active reader that illuminates the room and reads information from a passive tag antenna. These systems have been implemented in the LF (12 {13 KHz), HF (13 MHz), UHF (860 { 960 MHz) frequency bands. Most RFID …
