Design of dipole array MIMO antenna for multiband and ultrawideband radiation applications in WiFi/Zigbee/WiMAX/satellite and mobile communications

This publication proposes a fabricated multiple input multiple output (MIMO) antenna geometry of multiple dipole arrays and its numerical findings through simulations. The role that antenna resonators have in antenna performance is explored. The antenna’s characteristics have been studied, such as its return loss, peak gain, bandwidth, polar plot, and electric field distribution. The proposed antennas described in the study can produce three to seven resonance bands, making them suitable for multiband, wideband, and short-band settings. With the radiator placed in a mirror image, a gain of ~ 27 dBi is seen in the design. This layout is successful at achieving a bandwidth of 0.98 GHz. The maximum bandwidth of 7.44 GHz was achieved in antenna design when the antenna was inverted and mounted vertically. We measure a peak gain of ~ 4.1 dBi for this antenna configuration. In addition, the suggested antenna may provide a multi-beam antenna radiation pattern, capable of producing both a narrow beam of 10° and a wide beam of 250°. The proposed antenna has numerous potential uses; the study’s findings can be applied to various wireless networking and telecommunications technologies, including Zigbee, WiFi, WiMAX, satellite, and 5G.
