Design of a Two-Element Antenna with a Fan Beam Pattern for Use in Telecommunication Systems

In this paper, an attempt is made to design an antenna to be used in different radar and telecommunication applications. Paying attention to antenna radiation is on the agenda And studies have been done on antenna radiation as well as their radiation pattern.Considering that the feature of the pattern with the vane feature is used in antennas with radar applications, it is also used in various telecommunication applications. In this article, an attempt has been made to increase the antenna's fan beam properties The designed antenna has two radiation elements And in the 3.5 GHz frequency band, it consists of a two-layer structure. The radiation elements are placed in the upper layer and the feeding network is located in the lower layer. The built dual antenna has an impedance bandwidth of 3.8-3.4 GHz.The maximum gain Hz is 6/76 dBi and the half power beam width is 44˚ and 104˚ in H- and E- planes.respectively which shows that this is fan beam antenna. The overall dimensions of the antenna are 105 × 32/3 ×3/708 mm square. The provided antenna is recommended for use in radar systems and 5G systems in the 3/5 GHz frequency band. According to the laboratory test of this antenna, it can be said that the theoretical and practicical results are in good agreement...
