ANALYSIS OF A MODIFIED GROUND PLANE MICROSTRIP PATCH ANTENNA USING CO-AXIAL FEED
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TECHNOLOGIES AND MANAGEMENT RESEARCH - Year 2018, Vol 5, Issue 2
Abstract
A wandered probe-fed rectangular microstrip patch antenna (RMPA) with rectangular slots on a finite ground plane with dielectric material substrate (4.4) is proposed in this paper. The proposed antenna finite ground plane dimension is only 18mm x 21mm. The simulated result shows two distinct resonant frequencies at 4.5 and 9.5 GHz. A 10-dB wide-impedance bandwidth of 1000 MHz and 4100 MHz ranging from 3.8-4.8 GHz and 5.9–10 GHz is achieved. The proposed antennas have achieved wider bandwidth (51.3%) with reasonable gain (4 dBi).
THE PROPERTIES OF LATERITE SOILS AS THEY AFFECTS THE STABILITY OF BITUMEN STABILISED BRICKS
The purpose of this study is to determine the properties of laterite soil and how they affect the stability of bitumen stabilized bricks. The samples for the study were disturbed samples sourced in seven locations in Ada...
RADON CONCENTRATION IN GROUND WATER OF DHAKA CITY, BANGLADESH
Water is the most important source of life and ground water may contain varying levels of radioactivity. So it is therefore important to measure radon concentration in ground water for public health and radiation protect...

CORRUPTION AND INSTITUTIONAL INTEGRITY: THE CASE OF BANGLADESH
This paper highlights the view that corruption can be combated if institutional integrity can be put into practice, i.e. ‘institutional integrity’ has been considered as a key strategy to curb corruption. Based on litera...
