<p>The widespread of coronavirus disease 2019 (COVID-19) pandemic led to a discovery that open distance learning (ODL) has turned out to be the only choice for teaching and learning by most institution (s) of higher learning (IHLs). In Malaysia, ODL is considered a new approach as physical laboratory practice has always been conducted for laboratory courses. This is a quantitative study which explores the perceptions of e-Lab among the students of bachelor’s in electrical and electronic engineering (EE) by focusing on the effectiveness and readiness in conducting the e-Lab. Simulation-based model is proposed for conducting the e-Lab using an interactive media and validated with the final score performance. With the future goals of improving the e-Lab in terms of delivering methods and engaging mediums between students and laboratory instructor, this study also discovered the levels of response from students’ perception to substitute the conventional laboratory by providing an equivalent and comparable learning experiences of the students.</p>

This paper is concerned on constructing, optimizing and analyzing the different thickness of substrate for aperture coupled microstrip antenna. The design is constructed with respect to 2.4GHz of centre frequency. Structures are design by using different substrate thickness ranging from 1.27mm to 2.54mm. The physical parameters are analyzed and optimized by using commercial computer simulation technology (CST) packages. The result of return loss (S 11 ), gain, voltage standing wave ratio (VSWR) and frequency for different substrate thickness will be carried out. The antenna was then to be measured by vector network analyzer (VNA) to carry out its S 11 and VSWR result. The result from simulation and measurement are compared. This antenna promised for various communication applications such as wireless and antenna application.Keywords-Microstrip patch antenna; aperture coupling; return loss (S 11 ); gain; voltage standing wave ratio (VSWR); computer simulation technology (CST); vector network analyzer (VNA)
