An electrically small planar passive UHF-RFID tag based on an edge-coupled split ring
resonator (EC-SRR) antenna is presented in this work. In order to explore the potentiality …

Physical limitations of antennas above infinite perfect electric conductor (PEC) ground
planes are determined using the stored electromagnetic energy. Stored energies are …

The fundamental limit for small antennas provides a guide to the effectiveness of designs.
Gustafsson et al., Yaghjian et al., and Mohammadpour-Aghdam et al. independently …

The radiation properties of split-ring resonators (SRRs) at their second resonance frequency
are studied for the first time in this work. In particular, the electric and magnetic dipole …

In this paper key challenges related to design, manufacturing and practical application of
small LTCC antennas are described and discussed. A summary of the state of the art in …

The physical size and material properties of antennas are major limiting factors of the
antenna performance. These limitations are usually manifested through parameters such as …

This paper presents a novel planar antenna structure with miniaturization capability that fits
in a small area, and which can be designed towards any arbitrary input impedance, for RFID …

Avui dia, la identificació automàtica i unívoca d'objectes s' està imposant com a necessitat
creixent a nivell global, degut al ràpid increment de la producció i del comerç mundial. En …

New lower physical bounds on the quality factor Q were recently reported in the literature by
Yaghjian et al, and Mohammadpour et al. Due to the approximations made in derivation of …

This paper provides an overview of the antenna integration problem with an illustration of
antenna integration for the next generation railway communication systems. The influence of …
