BACKGROUND Despite recent achievement in economic progress in India, the fruit of development has failed to secure a better nutritional status among all children of the country. Growing evidence suggest there exists a socio-economic gradient of childhood malnutrition in India. The present paper is an attempt to measure the extent of socio-economic(More)
— A single layer monopole hexagonal patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting two equal slots which are the combinations of two triangular and one rectangular slot at the upper right and lower left corner and middle point symmetrical Y-junction slot located from the conventional(More)
—A single layer monpole slotted patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting three equal slots which are same hexagonal structure at the upper right, upper left, lower left corner and a circle at the center from the conventional microstrip patch antenna. It is shown that the simulated(More)
In recent years, great interest was focused on microstrip antennas for their small volu mes, lo w profiles, excellent integration, lo w costs and good performance. W ith the continuous growth of wireless communication service and the constant miniaturization of co mmun ication equip ment, there are higher and higher demands for the volume of antennas,(More)
A dual-band deducted unequal arm Y-shaped printed antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically consists of Y-shaped slot in middle point located from the conventional microstrip patch antenna. It is shown that the simulated results are in acceptable agreement. More importantly, it is also shown that the(More)
—A single layer, single feed compact slotted patch antenna is thoroughly simulated in this paper. Resonant f requency has been reduced drastically by cutting three equal slots which are same hexagonal structure at the upper right, upper left and lower left corner from the conventional microstrip patch antenna. It is shown that the simulated results are in(More)
The properties and performance of DDR p + pnn + Wurtzite Gallium Nitride (Wz-GaN) Impatt diodes at Terahertz (THz) frequencies has been investigated for optimum bias current density through modeling and simulation technique. A double iterative computer method based on drift-diffusion model has been used to study the DC and small signal admittance properties(More)
The high-power generation capability of pulsed mode Silicon Double Drift Region (DDR) IMPATT devices has been studied by using generalized simulation software developed by the authors. The software is based on drift-diffusion modeling scheme, incorporating thermal design. After optimization of the device design, it is observed that a maximum efficiency of(More)
A single layer, single feed compact slotted patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting two irregular rectangular slots from the conventional microstrip patch antenna. It is shown that the simulated results are in acceptable. More importantly, it is also shown that the differentially-driven(More)
A single layer, single feed compact slotted patch antenna suitable for dual-band operations is thoroughly simulated in this paper. Patch antenna is basically a low cost, light weight, medium gain and narrowband antenna and suited for short-range microwave application such as a feeding element for other antennas and in research institutes as a reference(More)
