As Antenna resides between cable/waveguide and the medium air, the main function of antenna is to match impedance of the medium with the cable/waveguide impedance. Hence antenna is impedance transforming device. The second and most important function of antenna is to radiate the energy in the de...
An active windshield antenna has a first conductor extending parallel to a metal frame to the vertical line of symmetry of the latter, a second conductor extending in a bending point from said first conductor along the symmetry line, an amplifier has separate transmission paths for a low ...
Antenna Gain:The parameter that measures the degree of directivity of the antenna’s radial pattern is known as gain. An antenna with a higher gain is more effective in its radiation pattern. Antennas are designed in such a way that power raises in the wanted direction and decreases in unwant...
Dipole Antenna:Comprising two conductive elements, it’s one of the most basic and widely used omni-directional antennas. The classic “rabbit ears” TV antenna is a type of dipole. Loop Antenna:As the name suggests, this antenna is in the shape of a loop. It’s often used in AM radio...
The space borne system at the L-Band utilizes thecircular polarization signalsin transmission as well as receiving signals. This changing orientation of the transmission as well as receiving CP antenna as satellites go round the earth doesn’t result in polarization fading just like it does for th...
Learn the antenna definition, understand the function of an antenna, and discover how radio signals are transmitted. Explore the different types of...

Thepolarization of the loop antennais horizontally or vertically polarized based on the position of the feed. The horizontal polarization is specified at the middle of the horizontal side whereas the vertical polarization is specified at the middle of the vertical side based on the antenna’s shape...
These antennas can transfer radio waves from a particular area to a certain area. Mini panel antennas can enhance WiFi signal indoors. Also, they can be used instead of a paddle antenna on a router. These antennas need to be focused in the direction where you would be transferring a signal...
