The current paper presents the design and implementation of a reflector antenna for microwave communications. The use of reflector antennas is involved in many applications. In the previous work, they designed a patch antenna for 5G applications. In the designing of the patch antenna, a large amount of bandwidth is used and the loss of the reflection coefficient is much higher. To overcome the above issues, this paper explains a parabolic reflector antenna for satellite and microwave communication. It gives us better results and high performance when compared to the patch antenna. These better results play an important role in microwave communication and satellite communication. This simple feature has made the parabolic reflector the most widely used optical and radio equipment in astronomical telescopes and, more recently, in microwave communication technology, including satellite communications, for transmission and reception of antennas. As well as the concentration of solar radiation in solar power as a commercial source of energy plants.The parameters used in this paper for the antenna are impedance matching, reflection coefficient, and bandwidth of the designed antenna.
