In this paper an approach of obtaining optimal planar antenna arrays consisting of omnidirectional sensors is proposed. The novelty of the proposed approach is to apply an exact expression of the Cramer-Rao lower bound for an arbitrary planar antenna arra... see more

Saat ini ITS sedang berpartisipasi dalam sebuah komunitas bernama INSPIRE yang mengerjakan sebuah proyek pembuatan satelit nano.  Salah satu kriteria dari satelit tersebut adalah memiliki antena mikrostrip dengan frekuensi 2,4 GHz. Pada tugas akhir i... see more

Worldwide, defense technologies are rapidly evolving and are currently aiming at integrating diverse functionalities like Radar, Electronic Warfare, Communications, etc., on a singular miniaturized platform. Hence, it cannot be denied that the advancement... see more

The element failure of digital beam forming array antenna systems used in defence equipment increases the side lobe power level which distorts the beam pattern of the antenna array. The problem of array failure correction becomes more complex when null st... see more

This dissertation presents a beam forming network (BFN) for phased array antenna-based on coherently radiating periodic structure (CORPS). The elements of CORPS are selected in such a way to obtain broad band characteristics, good return loss and good iso... see more

The object of research is the technology and technical means to clear the voids during the underground mining of ores in the disturbed arrays. One of the most problematic places is the filling of man-made voids that affect the occurrence and redistributio... see more

The presence of minerals ore especially the presence of mercury is the importantthing to be noticed in the mining field. Minerals ore have high economical value inmining industry, but mercury can be a pollution in soil. Geolectrical Resistivitymethods wit... see more

This paper describes the design and evaluation of a broadside printed dipole array for WLAN applications. The technique used allows to design a reduce antenna to radiate walkways and corridors, like those found in malls. The array was built in traditional... see more
