This paper presents several topics on the beam efficiency of a reflector antenna. (i) A simple definition for the main beam is suggested for calculating beam efficiency. This definition is related to the reflector aperture diameter, but is independent of the feed edge taper. Use of this ...

A spacecraft has a high efficiency multi-beam antenna (MBA) system that serves a coverage region on the Earth. The coverage region subtends an angle, when viewed from the spacecraft, of at least ten degrees. The antenna system provides, within the coverage region, at least sixteen spot be...
Then, combining the needs of practical engineering, a ring-focus elliptical beam reflector antenna is manufactured and tested. The gain at center frequency (12???GHz) is 37.7???dBi with an aperture efficiency of 74.6%. 3???dB beam-width in ??=0?? and ??=90?? plane is 2.6?? and ...

They continue to be improved as the need for accuracy, efficiency, and more advanced metrics become increasingly important. In past years, a dish antenna has been widely used to transmit (Tx) and receive (Rx) signals where directivity is important and many of those systems work well at...
GA is one of optimizing technique works based on genetic concepts. In addition the proposed method increases the efficiency of the smart antenna. The comparative and analytical results prove the performance of the proposed method over the other existing methods.Hardeep Singh...
7 represent the efficiency of the transmitting antenna. Truncation losses dominate when a/ω0 is small, whereas obscuration losses dominate when a/ω0 is large. Maximum efficiency is obtained whenever a/ω0 satisfies the equality Sign in to download full-size image Fig. 7. Far-field axial ...
