H-plane array configuration of different elements of balance antipodal Vivaldi antenna is presented in this paper. The configuration of an antenna is based on the improvement in radiation characteristics of BAVA. The use of two and four elements placed in h-plane configuration is considered. Each single element antenna is printed on FR4 substrate o

In this paper, A Novel 1 to 4 modified Wilkinson power divider operating over the frequency range of (3 GHz to 8 GHz) is proposed. The design perception of the proposed divider based on two different stages and printed on FR4 (Epoxy laminate material) with the thickness of 1.57mm and ϵr =4.3 respectively. The modified design of this power divider

In this paper, an Ultra-wideband Balance Antipodal Vivaldi Antenna in planar and h-plane array configuration is presented. The comparison of four elements of BAVA array in both planes has been observed. Each element of an antenna printed on the glass-reinforced epoxy laminate material (FR4) with a thickness of 1.5mm and relative permittivity of 4.3

Quality assurance in higher education is a hot topic with the increased number of students graduating from postgraduate programs offered by the higher education institutions. This qualitative study aimed to look at the history and the current status of the quality assurance mechanisms in the Maldives; identify its strengths and weaknesses; and make

This paper present a recognition technique of metal placed inside and between two walls. A unique scheme of recognition of metallic objects through Ultra Wide Band (UWB) Modified Antipodal Vivaldi Antenna (MAVA) frequency range of (3.1GHz to 10.6 GHz) is presented in this paper.The working mechanism of detection system based on Time Domain Reflectr

In this paper, the examination of recognition technology along with imaging system intended for the identification of metallic object inside or in the middle of two walls. The UWB frequency is used by ground–penetrating radar (GPR). The working mechanism of illuminating structure is centered on Time Domain Reflectrometry (TDR) by means of through

The functional characteristics and parametric study of Ultra-Wideband Antipodal Vivaldi Antenna along with end-fire radiation pattern via UWB frequency range for radar as well as microwave imaging application has presented in this paper. The comparative study of different kind of AVA according to their structure and dimension has been proposed. Alt

The rapid development of technology has enabled the creation of artificial intelligence. Even the most vocal critics against artificial intelligence and automated systems acknowledge the tremendous benefits offered by this new technology as can be seen in various aspects of human life from trade and commerce, healthcare, safety and security, transp

Beberapa hari yang lalu, negara kita dikejutkan sekali lagi dengan penularan penyakit Japanese Encephalitis atau JE di Sarawak. Sejak awal tahun ini, sebanyak lima kes jangkitan telah dilaporkan iaitu menyamai separuh daripada jumlah keseluruhan kes berbanding tahun lalu. Jumlah ini dikhuatiri makin meningkat dan penyakit ini boleh merebak menjadi

Bulan Ramadhan adalah bulan yang seringkali ditunggu oleh setiap umat Islam. Bukan sahaja kerana kemeriahan dan keberkatannya, tetapi juga faedah kesihatan yang bakal diperolehi bagi penganut yang mengamalkan ibadah berpuasa selama sebulan. Umat Islam dituntut untuk mengawal diri daripada mengikut hawa nafsu, termasuklah dari makan dan minum, iaitu
