How to design a reconfigurable antenna? Step-by-step process.

-
Determine the frequency range and bandwidth requirements for the antenna. Choose an appropriate antenna structure, such as a patch antenna, microstrip antenna, or planar inverted-F antenna (PIFA). Choose the reconfigurable component, such as PIN diodes, switches, or varactor diodes. Design the impedance matching network, which is essential for optimal performance of the antenna. Simulate the antenna using electromagnetic simulation software, such as CST Microwave Studio, Ansys HFSS, or Keysight ADS, to verify its performance. Fabricate the antenna and integrate the reconfigurable component. Test the antenna in an anechoic chamber to verify its performance and ensure that it meets the requirements. Repeat steps 5-7 as necessary to optimize the antenna's performance. Note: These are general steps for designing a reconfigurable antenna and may vary depending on the specific requirements and constraints of the application.

Spotters in "Environment and Health: Mosquitoes- Anopheles" for CFM & MPH students

-
Image
Anopheles Mosquito: Also known as the sophisticated mosquito. The flight range is 3-5 km. Around 45 species of anopheles mosquitoes have been found in India but only a few of them have been incriminated as vectors or carriers of malaria. These are An. fluviatilis & An. minimum (foot-hill regions), An. sundaicus & An. stephensi (coastal regions) and An culicifacies & An. philippinensis (planes). 1. Eggs: Important points: Eggs laid on the surface of the clean water. 100-250 at a time. This stage lasts for 1-2 days. Laid singly, boat-shaped & possess lateral floats. 2. Larva: Important points: The larva is a free-swimming creature. Passes through 4 stages called ' instars ' with moulting between each stage. Floats horizontally in water/ rests parallel to the water surface. No siphon tube at the tip of its abdomen.  Palmate hairs present on abdominal segments. 3. Pupa: Important points: The pupa is comma-shaped in appearance, with a large rounded cephalothorax and...

Bajaj Set to Launch CNG Motorcycle by June 2024

-
The wait for India's first CNG motorcycle is finally coming to an end, with Bajaj Auto gearing up for its launch. According to recent reports, the company could unveil the motorcycle as early as June this year. Earlier speculations suggested a launch by 2025, but now it seems Bajaj is expediting the process. While details about the motorcycle's name remain scarce, the company aims to cater to various segments ranging from 100cc to 160cc. Rakesh Sharma, Executive Director of Bajaj Auto, highlighted the efficiency of CNG over diesel in terms of cleaner emissions. While CNG produces negligible particulate matter emissions compared to diesel, it's not a zero-emission fuel. Hence, Bajaj is expanding its portfolio to include models like LPG, compressed natural gas (CNG), and ethanol-blended fuel in the coming years. The forthcoming CNG motorcycle, possibly codenamed "Brujar E101," is in its final stages of development. Prototypes have been tested, with an estimated mile...
