Triple-band mmWave 4-port MIMO antenna with enhanced isolation for IoT and vehicular communication systems
This paper presents a compact 4 × 4 multiple input multiple output antenna designed to operate at triple-band frequencies of 28, 29.58 and 32.82 GHz. The antenna is fabricated on a Rogers RT 5880 substrate with overall dimensions of 13 × 13 × 0.254 mm3. The antenna operates over three frequency bands: 27.70–28.32 GHz,...
