Modern Small Antennas

Abstract

If you are involved in designing and developing small antennas, this complete cutting-edge guide covers everything you need to know. From fundamentals and basic theory to design optimization, evaluation, measurements and simulation techniques, all the essential information is included. You will also get many practical examples from a range of wireless systems, whilst a glossary is provided to bring you up to speed on the latest terminology. A wide variety of small antennas is covered, and design and practice steps are described for each type: electrically small, functionally small, physically constrained small and physically small. Whether you are a professional in industry, a researcher, or a graduate student, this is your essential guide to small antennas.

On the multi‐resonant antennas: Theory, history, and new development

“…In that way, more filtering antennas with enhanced performance can be designed and implemented. Moreover, the multi‐resonant antenna design technique is also expected to emerge with other advanced techniques, that is, electromagnetic band‐gap (EBG) materials and meta‐surface, and this may lead to more novel, multi‐resonant antenna designs.…”

“…In addition, low loss tangent reduces the dielectric loss which increases the antenna efficiency . Multiple such attempts have been made in design of ESA and antenna performance enhancement of ESA . The proposed antenna is fed by the 50 Ω SMA connector.…”

“…1,10 Multiple such attempts have been made in design of ESA and antenna performance enhancement of ESA. 3,[22][23][24][25][26][27][28][29][30][31][32] The proposed antenna is fed by the 50 X SMA connector. SMA connector at top and bottom side is connected by soldering to feed line and ground plane.…”

“…Further, medical equipments are usually small in size, which significantly increases the demand of electrically small antennas (ESA) . However, ESA suffers in terms of low gain and typically offers narrow bandwidth . Most of the researchers have been working to improve the bandwidth and gain simultaneously of electrically small patch antenna by varied techniques proposed in the literature .…”

“…1,2 However, ESA suffers in terms of low gain and typically offers narrow bandwidth. [3][4][5][6][7] Most of the researchers have been working to improve the bandwidth and gain simultaneously of electrically small patch antenna by varied techniques proposed in the literature. [8][9][10][11] Addition of superstrate to the antenna is one of the techniques to improve the bandwidth and gain.…”
