Item type:Publication, Design 2.4/5.8 GHz microstrip-to-coplanar strip transition(2007-12-01); ; Chongcheawchamnan, MitchaiA 2.4/5.8 GHz microstrip (MS)-to-coplanar stripline (CFS) transition (industrial-scientific-medical bands) is presented in this paper. The transition can operate at two bands simultaneously with a stepped impedance transformer and stepped impedance open stub. The circuit is proven with a design on RF060 substrate. Simulated and experimental results of the transitions connected in back-to-back style are in good agreement. The back-to-back transition exhibits return and insertion losses, which are better than 15 dB and 3 dB, respectively. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Electromagnetic wave scattering on 2D PEC cylinders using complex source point techniques and uniform geometrical theory of diffraction(2010-07-30); An analysis of the path loss in the durian orchard is presented by using the complex source point technique (CSP) and the uniform geometrical theory of diffraction (UTD). The 2D Gaussian beams (GBs) expansion scattered by 2D cylindrical structures are presented. The GB can be generated by using the CSP. The GBs expansion can provides an efficient way of the synthesis of the radiation pattern of the antenna. The cylindrical structures are preliminarily assumed to be a perfect electric conductor (PEC). The source (square patch antenna) is located on a durian. The CST-program uses to simulate the source pattern including the effect of durian for the UTD calculation. The CSP-UTD is applied to analyze the scattered fields from the cylindrical structures. The multi-path propagation and the path loss prediction in various aspects are then obtained. Also, the exact solution of the CSP scattered by a cylindrical is used to compare the UTD results. The good agreements are obtained in this work. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Path loss model and measurements of 5.8 ghz wireless network in durian garden(2008-12-01); ; This paper presents the path loss model and measurement of wireless network in durian garden at 5.8 GHz. This study is important in wireless communication system for predication and design the communication system of durian garden such as communication range, power transfer, position of transmitting and receiving antenna. From the results, it is obvious that the path loss at the distance of 128 m from the transmitter is less than -50 dB. © 2008 IEEE. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Magnetic field distributions of two-slot array antenna on a concentric sectoral cylindrical resonator excited by a coupling slot(2008-12-01); in this paper, the magnetic field distribution of two-slot array antenna on a concentric sectoral cylindrical resonator excited by a coupling slot is presented. The correlations between the field distributions of the antenna and the mode-based field distributions are presented. The radiation pattern, magnetic field distribution and magnitude of S11 are investigated in the terms of the length of the sectoral resonator. It shows that the TE112 mode has degenerated to the magnitude of S11 for the circumferential slot array antenna. The results provide useful information for the design of switched-beam array antenna on the concentric sectoral cylindrical resonators. ©2008 IEEE.
