Performance comparison of serial and corporate feeding networks in a rectangular Microstrip patch antenna array
(Kolej Universiti Teknologi Tun Hussein Onn, 2006-12-19)
One of the important aspects of a microstrip patch antenna array is the availability of the two feeding networks applicable to them, which are the serial and corporate feeding. A good impedance matching and optimal radiation ...
Performance modeling and simulation of microstrip dipole array antenna for WLAN application
(Institute of Electrical and Electronics Engineering (IEEE), 2008)
This paper proposed a performance simulation of a two-element, microstrip dipole array antenna for WLAN application. Simulation is done using two different simulation techniques, the circuit model (CM) derived from the ...
Small rectangular parasitic plane as patch antenna ground plane for broadband WLAN application
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
This paper proposed a microstrip patch antenna for broadband WLAN application. The antenna is based on an octagonal patch, which is simulated and analyzed by using Microwave Office (MWO) for WLAN applications. The designed ...
Theoretical investigation of far-infrared optical behaviors in asymmentrical first-order ferroelectrtric thick film
(Universiti Putra Malaysia (UPM), 2005-12-06)
This paper gives a detailed, fully numerical approach to investigate the behavior of far-infrared (FIR) waves in the first-order of asymmetrical thick film ferroelectrics on semiconductor substrate. The theoretical calculation ...
Surface state on first-order ferroelectrics
(Springer Berlin / Heidelberg, 2006)
In the presence of a surface the Landau-Devonshire equations of ferroelectricity must be extended to include a boundary condition. For a ferroelectric with a second-order transition in the case when the polarization p(z) ...
The phenomenological theory of Far-Infrared spectroscopy for a ferroelectric fim system
(Malaysian Institute of Physics & National University of Malaysia, 2004-10-05)
We describe a detailed phenomenological theory of far-infrared (FIR) spectroscopy in symmetric and asymmetric ferroelectric (FE) film for the second and first-order phase transition. For the asymmetric FE film, a silicon ...
