Ka mekhoa ea antenna ea setso, sebaka se pakeng tsa lintho li tlameha ho ba ka tlase ho halofo ea wavelength (λ / 2) ho qoba tšitiso. Molao-motheo ona o sebetsa ka mokhoa o lekanang ho isa ho 5G ho lokisa li-antenas. Ka mohlala, karolo ea makala a hlakisang ka bongata ba 28 GHZ e na le sebaka sa motlakase sa ba ka bang 5 mm.
