“…The optimized dimensions of the antenna are tabulated in Table I. The metallic ground plane of size 80.75 × 28.30 mm 2 at the antenna's back fits within the substrate dimensions and avoids integration of huge metallic ground plane as suggested in [9]. Moreover, the proposed structure suggests a use of metallic wire-bond contacts by using Alwires for frequency tuning, thus avoids use of switching devices/ICs [9] and complex biasing circuitries involved.…”

This paper presents the design and performance analysis of a planar, miniaturized meander-line dipole antenna designed for short-range wireless communication links. The proposed compact antenna has a size of 0.08λo × 0.03λo (at fo = 288 MHz) and designed on a sapphire substrate with optimized dimensions of 80.75 × 31.3 × 1.5 mm 3 . This electrically small antenna design is comprised of symmetric C-shaped resonators with meandered lines and gaps to perform frequency tuning. Simulated results show that the antenna can be effectively tuned to 288 MHz, 298 MHz and 310 MHz by applying structural reconfigurations. The radiation pattern in all the suggested frequency bands is perfectly omni-directional. The proposed antenna due to highly compact size is a potential candidate for the short-range wireless networks.

“…The effectiveness of such a system depends primarily on the correct design of the transponder antenna. The subject of RFID antenna synthesis has been discussed frequently in the research literature; consideration of the design of an effective electronic tag is not new [2][3][4][5][6]. Unfortunately, there are no universal 'off-the-shelf' devices that could be used directly in non-standard utility applications.…”

The problem considered in the paper concerns the synthesis process of antennas for autonomous semi-passive RFID transponder/sensors dedicated to active glazing units. Glazing units are frequently used in modern multi-storey buildings to create amazing facades. When they are integrated with photovoltaic (PV) modules, active units are obtained. It is desirable, mainly for economic reasons and in order to ensure the high efficiency of a micro-photovoltaic power plant, that active glazing units are equipped with a system for monitoring their operating parameters. In connection with this, design problems occur that fall within the fields of sensor technology and radio communications. The main purpose of the presented study was to prepare appropriate input data for design tools used in the synthesis of antenna systems in the UHF band. Many important issues are considered including: proximity to structural elements of the building facade and PV cells, which disturbs the shape of the radiation pattern and affects the impedance parameters of the antenna system; the need to ensure easy integration of the RFID sensor and the specified object, without significant interference in the production of glazing units; appropriate shaping of the radiation pattern in order to enable reading and writing of the RFID tag from both inside and outside the building; impedance matching to the selected RFID chip in the broadest possible frequency range, etc.

“…The implementation in the ultra-high frequency (UHF) band (860-960 MHz) of a passive radio frequency identification (RFID) tag is growing substantially due to its higher reading rate, enhanced reading range, and reduced tag size [1] relative to the low frequency (30-300 kHz) and high frequency bands [2]. It is widely used in inventory systems, distribution logistics, retail sales, industries, and general detection systems [3][4][5]. A typical RFID system consists of several components: an RFID interrogator and an RFID tag antenna, which comprises an IC chip and an antenna [6].…”

A metal mountable UHF RFID tag antenna with a low-profile folded dipole structure is proposed. It is fabricated on a single layer of polytetrafluoroethylene (PTFE) dielectric laminate. It is composed of two symmetrical C-shape resonators integrated with the outer strip lines. The IC chip's terminals are connected directly to the center of the C-shaped resonators. The outer strip lines are integrated with the C-shaped resonators, which function to lower the reflection coefficient so as to match the IC chip impedance. In particular, the outer strip lines increase the inductive reactance of the antenna impedance in order to realize IC chip impedance. The design has a simple structure, due to the fact that it lacks any metallic vias. Moreover, the gain of the tag antenna can be enhanced when positioned on a large metallic sheet. Installed on a 40 × 40 cm 2 metallic plate, the total gain of the proposed tag antenna is 3 dB, with a maximum reading range of 5.77 m, while it is 3.92 m in free space. The simulation results were in excellent agreement with the fabricated design results.
