The antenna is an arrangement of aerial electrical conductors designed to transmit or receive radio waves that is a class of electromagnetic waves. In other terms, antennas mainly convert radio frequency electrical currents into electromagnetic waves. Antennas are used in systems such as radio and television broadcasting point-to-point radio commun...
The omni directional antenna is an antenna system that radiates power uniformly in all directions. The only 3 dimensional omni directional antenna is the isotropic antenna, a hypothetical construct derived from actual antenna radiation patterns and used as a suggestion for specifying antenna gain and radio system effective radiated power. Practical...
Antenna is an electronic device. It is an arrangement of aerial electronic conductors. These are designed to transmit or receive radio waves or electromagnetic waves. Heinrich Hertz discovered an antenna in 1886. Basically the antennas convert radio frequency electric current into an electromagnetic wave. Antennas have a wide range of usage. They a...
Dipole antenna is nothing but an antenna with two poles. It is the simplest type of antenna. A dipole antenna is an aerial half a wavelength long. It is an electrical device that is used to send or receive radio or television signals. It consists of two rods connected to a transmission line at the center. It has maximum radiations at right...
The elements of the antenna array means the collection of all the similar radiation and elements related to the antenna, where the counting of the elements starts from 1 till N number. The similarity of the elements is judged on the basis of the same frequency, which means to derive voltage of each element one has fixed amplitude and phase angle. T...
Portugal was a world power in 15th and 16th century but was reduced to rubbles during an earthquake in 1755, Napoleon’s Invasion and Brazil’s Independence. Sharing the Iberian Peninsula with Spain and bordering Atlantic Ocean by both west and south coast it is popular for its long and varied coastline, sunny climate an...
A bed canopy is a material hung from the top of a bed that falls down to the edges and rests on the floor. It primarily helps in keeping away mosquitoes. It also helps in retaining heat inside and maintaining the warmth. It also looks good and creates a glamorous ambience.
