Antenna Design of Book Layout Design of Antenna In this article we use dipole antenna as tag antenna, and the polarization direction is.
This book deals with the design, numerical simulation, state of the art fabrication processes and methods, qualitative and quantitative tests, and measurement techniques of wearable and flexible antennas of different topologies, such as: Planar Inverted.
You learn how to select and design proper broadband microstrip antenna configurations for compact, tunable, dual-band and circular polarization applications. Moreover, the book compares all the broadband techniques and suggests the most attractive configuration.
Extensively referenced with over illustrations and equations. A multiband coplanar waveguide (CPW)-fed antenna loaded with metamaterial unit cell for GSM, WLAN, LTE-A, and 5G Wi-Fi applications is presented in this paper. The proposed metamaterial structure is a combination of various symmetric split-ring resonators (SSRR) and its characteristics were investigated for two major axes directions at (x and y-axis) wave propagation through the material.
Broadband Microstrip Antennas by Professor Girish Kumar and Dr. Ray is wholly dedicated to broadband microstrip antenna designs only. After the first introductory chapter, there are seven chapters on various designs for microstrip patches, and another chapter dealing with tunable and dual-frequency microstrip antennas.
The aim of this book chapter is to provide a basic understanding of RF energy harvesting (RFEH) techniques, describe the underlying electronics hardware design, show the current state-of-the-art applications and commercially available products, and finally expand to future applications and challenges ahead.
In the present design, we focus on the two GSM and WiFi frequency bands ( MHz, 1, MHz and 2, MHz, respectively). Our architecture choice consists of a single multi-resonant antenna with a single rectifying section: this way, the unwanted EM-couplings always present in multi-antenna solutions are avoided, as well as the minimization of.

Thus the reader antenna should be a circularly polarized antenna, in order to avoid the polarization loss when the orientation of the identified object is changed.
Meanwhile, the reader antenna should have low profile and realize miniaturization, some of which should operate at more than one band. Average SAR and SAR distribution in man exposed to MHz RFR.
