Parabola Antena

Parabola Antena. Parabolic Reflectors are Microwave antennas For better understanding of these antennas the concept of parabolic reflector has to be discussed Frequency Range The frequency range used for the application of Parabolic reflector antennas is above 1MHz These antennas are widely used for radio and wireless applications Principle of Operation.

OverviewDesignTypesFeed patternGainRadiation patternA parabolic antenna is an antenna that uses a parabolic reflector a curved surface with the crosssectional shape of a parabola to direct the radio waves The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish The main advantage of a parabolic antenna is that it has high directivity It functions similarly to a searchlight or flashlig Text under.

LECTURE 12: Reflector Antennas

PDF fileLECTURE 19 Reflector Antennas 1 Introduction Highgain antennas are required for longdistance radio communications (radiorelay links and satellite links) highresolution radars radioastronomy etc Reflector systems are probably the most wgain antennas idely used highThey can easily achieve gains of above 30 dB for microwave and higher frequencies Reflector.

Advantages and disadvantages of Parabolic Reflector …

The parabolic reflector antenna gain is calculated as the gain over an isotropic source ie relative to a source that radiates equally in all directions This is a theoretical source that is used as the benchmark against which most antennas are compared The gain is quoted in this manner is denoted as dBi How parabolas are applied in parabolic dishes? A parabolic dish.
