Performance analysis of circularly polarized dual annular ring patch antenna for MIMO satellite application

High gain multi-band circularly polarized wearable leaky wave zipper MIMO antenna

“…[ 17 , 23 , [26] , [27] , [28] ] considered more MIMO diversity characteristics like DG and ECC. Though all were wearables, not all assessed the possibility of polarization except for [ 26 , 27 , 29 ]. [ 23 , 26 ] offered UWB antennas covering multiple bands, but their gains were too low even with large sizes.…”

“…[ 23 , 26 ] offered UWB antennas covering multiple bands, but their gains were too low even with large sizes. Notably [ 29 , 30 ], considered all parameters, offering wideband and multiband features, maximum gains up to 7.1 dBi, diversity gains of less than 10 dB, and ECC of 0.002 and 0.0001, respectively. Despite their notable achievements, the proposed antenna demonstrates superior performance regarding the number of working bands, gain, dimensions, radiation efficiency, DG, and ECC.…”

5.8 GHz Helical Antenna Design and Analysis for Drone and Ground Station Communication

“…For tracking large moving objects, patch antennas with array configuration are used as well as parabolic dish antennas. However, it is difficult to obtain high gain with patch antennas [15][16][17]. The primary reason for using helical antennas in satellite communication is that they can be designed with circular polarization and provide high gain [11].…”
