This work proposes, builds, and manufactures a small, high-gain MIMO antenna for radar applications. Using a Parasitic elements such as director & reflector show a simple method for increasing the gain and bandwidth of a Yagi-Uda Antenna. Using a Parasitic elements such as director and reflector show a simple method for increasing the gain and bandwidth of a Yagi-Uda Antenna. Using a nearby parasitic director and reflector. Also, it shows a simple method for increasing the gain and bandwidth of a Yagi–Uda antenna. A strip with a parasitic director is placed close to the top dipole element to improve the gain as well as bandwidth attributes of the Yagi–Uda antenna. The antenna performance parameters are investigated for 1 × 2 MIMO, cross dipole MIMO antenna (1 × 4), and an array configuration (two 1 × 4). It has high gain and operates in the S-band (2 GHz–4 GHz). This antenna supports three bands and has a highest maximum directive gain of 12.5 dBi at 2.5 GHz and a bandwidth of 0.21 GHz. It is made of FR4 substrate. The suggested structure is 120 mm × 70 mm in size. Due to its high gain and less return loss, this antenna is better suited to radar applications. |
