چکیده

─ Normal mode helical antennas are widely used for RFID and mobile communications applications due to their relatively small size and omni-directional radiation pattern. However, their highly curved geometry can make the design and analysis of helical antennas that are part of larger complex structures quite difficult. A simplified model is proposed that replaces the curved helix with straight wires and lumped elements. The simplified model can be used to reduce the complexity of full-wave models that include a helical antenna. It also can be used to estimate the performance of a helical antenna without fullwave modeling of the helical structure. Index Terms─ Helical Antennas, RFID.

On Modeling and Personal Dosimetry of Cellular Telephone Helical Antennas with the FDTD Code - Antennas and Propagation, IEEE Transactions on

In this paper, a novel method to model helical antennas working in the normal mode, as well as helix-monopole antennas with finite-difference time-domain (FDTD) code is presented. This method is particularly useful to model antennas used for personal wireless communication handsets, where the fairly small dimensions of the helical antennas with respect to wavelength and the grid cell size do no...

Design Equation for Self Resonant Structures of Very Small Normal - Mode Helical Antennas

Recently, normal-mode helical antennas (NMHA) are employed as very small antennas for metal plate proximity uses [1] ~ [3]. In order to obtain efficient radiation, the self resonant condition of a NMHA should be satisfied. In this condition, the inductive reactance and the capacitive reactance of a NMHA are cancelled. As for the inductance, Wheeler presented an equation employing structural par...

Helicon wave excitation with helical antennas

Components of the wave magnetic field in a helicon discharge have been measured with a single-turn, coaxial magnetic probe, Leftand right-handed helical antennas, as well as plane-polarized antennas, were used; and the results were compared with the field patterns computed for a nonuniform plasma. The results show that the right-hand circularly polarized mode is preferentially excited with all ...

Compact helical antenna for smart implant applications

Smart implants are envisioned to revolutionize personal health care by assessing physiological processes, for example, upon wound healing, and communicating these data to a patient or medical doctor. The compactness of the implants is crucial to minimize discomfort during and after implantation. The key challenge in realizing small-sized smart implants is high-volume costand time-efficient fabr...

Determination of Resonance Frequency of Dominant and Higher Order Modes in Thin and Thick Circular Microstrip Patch Antennas with Superstrate by MWM (RESEARCH NOTE)

An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...
