Design of a compact four-port mmWave MIMO antenna with resonator-based band rejection
This paper introduces a compact ultra-wideband MIMO antenna featuring an integrated notch-band response. Wideband operation is achieved through the combined use of meandered feed lines, a modified Y-shaped radiating element, and a defected ground structure. The antenna occupies a compact volume of 12 x 8 x 1.6 mm³ and...
