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, A multibeam antenna using quasi-optical antenna-mixers(2008-06-02); A multibeam antenna could be designed without using a complicated feeding system by using quasi-optical antenna-mixers. Accurate beam directions could be obtained when practical antenna patterns was taken into account in the design. The effectiveness of a three-beam antenna is demonstrated at K-band showing accurate beam directions which is very useful in modern wireless communications. © 2007 Elsevier GmbH.

Item type:Publication, Phased array of switched-beam elements and its applications(2009-12-01)This paper describes principle of a phased array of switched-beam elements (PASE). Variety of radiation patterns can be produced using four one-bit phase shifters and beam-switchable array elements. Some interesting applications of this antenna are illustrated. ©2009 IEEE. - 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.
