Impedance and quality factor of mutually coupled multiport antennas
نویسنده
چکیده
In this study, expressions for the radiation quality factor Q and the input impedance seen at any terminal of a multiport antenna are derived. It is shown computationally that because of the possibility to adjust the antenna current distribution through suitable feeding/loading a multiport antenna can perform lower Qs than a similar single-port antenna. © 2008 Wiley Periodicals, Inc.

Introduction The microstrip patch antennas are widely used in modern communication system due to low profile, low weight, low cost However, the antennas suffered from narrow bandwidth and low gain.[6 The major need for modern communication devices is to operate at wider band such as to support high speed internet, multimedia communication and similarly many more broadband services, this is achi...
متن کاملA Method of Phase Control and Impedance Matching of Mutually Coupled ICRF Antennas in LHD
In the Large Helical Device (LHD), the installation of a pair of ion cyclotron range of frequencies (ICRF) antennas from upper and lower ports is planned. These antennas are geometrically symmetrical and located side by side. By changing the current phase on the straps, the wave number parallel to the magnetic field line can be controlled. However, antenna impedances will also be changed and re...
متن کاملA Fuzzy Model for Computing Input Impedance of Two Coupled Dipole Antennas in the Echelon Form
In this paper, the previously introduced fuzzy modeling method is used to model the input impedance of two coupled dipole antennas in the echelon form. The initial data of two coupled dipole antennas in the parallel and collinear form, which are required for the model, are obtained using the MoM (Method of Moments). Then, the knowledge of two coupled dipole antennas in the echelon form is easil...
