Design equations of Rectangular Microstrip Patch Antenna

-
Image
Following design equation can be used to calculate the width and length of rectangular microstrip patch antenna and simulation of 2.4 GHz inset-feed rectangular patch antenna can be found in follwing video.  Microstrip antenna with inset-feed line                           Part-1 Design step for the calculation of W and L Step-1 : To calcualte width 'W' use follwing formula Step-2:   Calculate the effective dielectric constant using formula below. Here    ' ε r '  is relative  dielectric constant of the material. 'h' is height of the substrate and W is the width of patch calculated in first step. Step-3:   Calculate ΔL using formula below. Step-4:   Calculate length of the patch using formula below. v 0    is speed of light in free space. Part-2 Feedline calculation Step-1:   Calculate the input impdedance of the patch using follwing formula. (Typically between 200  Ω  to 250  Ω. You can assume 225  Ω for simplic

ORS : A boon in dehydration

-
Image
What is ORS? Oral re-hydration salts: It is a glucose-electrolyte formula given by WHO/UNICEF, used for correction of acute diarrhea due to all causes and dehydration in all age groups with aim to reduce mortality. It is available in powder form in sachets/ ready-made solution or it can be easily made at home. How it works? The combination of electrolytes and sugar together stimulates water and electrolyte absorption from the gut and hence  capable of correcting water and electrolyte deficit in conditions such as diarrhea and vomiting. Reasons to celebrate ORS day? ORS Day is celebrated every year on 29th July:  To spread awareness about the importance of Oral Rehydration Salts (ORS) as a low cost method of health intervention.   Among infants and young children, acute diarrhoeal diseases are one of the leading causes of mortality in many developing countries.   Dehydration particularly affects infants, children and old people.  Diarrhea normally lasts for several days, and leaves the

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

  Air direction: 1. Wind vane/ Wheather vane/ Wheathercock: Important points: It is an instrument  used for showing the direction of the wind. When the wind is sufficiently strong, the head of the arrow or cockerel indicates the direction from which the wind is blowing. The wind vane is placed high enough to avoid wind interference from objects, buildings, and trees like the top of towers, poles, etc. Types- Weathervane,  Wind Sock,  Digital Wind Vane Benefits: Safety from storms,  very helpful in activities like golf and boat sailing. Air speed: 2. Anemometer: Important points: It is a device used for measuring wind speed, direction & pressure. A common weather station instrument. Types- Cup, Vane, Hot-wire, Lesser doppler, Ultrasonic, Pin-pong ball, Plate & Tube anemometer Uses: helps  indicate  a change in weather patterns, such as an approaching  storm , which is important for  pilot s,  engineer s, and  climatologist s.
