Nowadays, frozen foods are well-known among Malaysia society. This is due to the modern lifestyles which require short food preparing times without neglecting the food nutritious. In supporting this requirement, the manipulation of vending machine is identified as a tool to promote modern and healthy living style, besides to simplify the cooking process. This paper describes the effort on designing...
We present a theoretical and experimental investigation into the effect of the motion of a printed circuit board (PCB) on the response of microelectromechanical systems (MEMS) devices to shock loading. For the theoretical part, a 2-DOF model is used, where the first degree of freedom accounts for the PCB. The second degree of freedom represents the motion of the MEMS microstructure. Low-g acceleration...
The design and experimental demonstrations of a microstrip patch antenna for broadband WLAN application are presented. The physical parameters of the antenna, including based on a diamond patch, antenna input impedance, antenna thickness and small parasitic plane as the ground plane dimensions, are studied. The influence of various parameters on antenna characteristics has been investigated using...
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 antenna exhibited a broad 230 MHz bandwidth, by using a small parasitic plane as the ground plane. Specification of this antenna, printed over a thin FR4 substrate of dielectric...
Introduction of parasitic plane as additional radiator helps to produce desired resonant frequencies, while helping to minimize the size of the antenna. A dual-band monopole antenna with parasitic plane is designed to satisfy dual-band applications, namely UMTS and WLAN 802.11. This work is an effort to investigate the effect of employing an inverted M-shaped parasitic plane, which introduces double...
