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

Image
Insecticides:   These are substances that are used to kill insects.  Pesticides:   It is a general term that includes  insecticides, fungicides rodenticides, herbicides,  disinfectants, repellents, and other chemicals used for the  control of pests. Insecticides are classified into 3 groups: Contact  poisons, Stomach poisons and Fumigants.  CONTACT  POISONS: These are those insecticides that kill insects primarily by contact  e.g., pyrethrum, DDT, HCH, dieldrin.  STOMACH POISONS: These  are those insecticides which when ingested cause the death of the  insects, e.g., Paris green, sodium fluoride.  FUMIGANTS: These are  those insecticides that give off vapours that have a lethal effect on  the insects, e.g., sulphur dioxide. 1. DDT  (Dichloro-diphenyl-trichloroethane) :  It was first  synthesized in 1874, by a German chemist, Ziedler . I ts insecticidal properties were discovered by the Swiss  scientist, Paul Muller in  1939 .  Important points: PROPERTIES: It is a white  amorphous

Spotters in "Environment and Health: Mosquito control Measures" for CFM & MPH students

-
Image
The integrated approach of mosquito control: This is an approach that avoids the excessive use of any one method (e.g insecticides) but tries to combine one or more methods with a view to obtain maximum results with minimum inputs and also to prevent environmental pollution with toxic chemicals & development of insecticide resistance. The various methods of mosquito control are as follows: 1. Anti- Larval Measures: (a) Environmental Control: Important Points: Source reduction : Mainly the elimination of mosquito breeding places by minor engineering methods such as  Filling- of cesspools & open ditches and arrangement for adequate collection, removal, and disposal of sewage & wastewater. Leveling & getting rid of water-holding containers such as discarded tins, empty pots, broken bottles, coconut shells, etc. Drainage of breeding places, and  Water management (e.g intermittent irrigation) & removal of aquatic plants or destruction by herbicides. Rendering the water u

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.
