Triple-Band MIMO Antenna with Integrated Decoupling Technology
This paper proposes an integrated decoupling method that improves the flexibility of multiport, multiband antenna design and simplifies the antenna structure. First, a dual-band L-type MIMO antenna with center frequencies of 2.6 GHz and 5.6 GHz is created using the neutralization-line decoupling met...

| description | This paper proposes an integrated decoupling method that improves the flexibility of multiport, multiband antenna design and simplifies the antenna structure. First, a dual-band L-type MIMO antenna with center frequencies of 2.6 GHz and 5.6 GHz is created using the neutralization-line decoupling method and then a dual-band L-type MIMO antenna covering the WiFi spectrum (2.3–2.5 GHz and 4.6–5.6 GHz) is created using the type-T branch decoupling technique. After demonstrating the efficacy of neutralization-line and T-branch decoupling technology for L-type antennas, a four-port L-type MIMO antenna covering 4.4–4.9 GHz, 5.4–6.1 GHz, and 7.0–7.4 GHz is proposed by combining the methods of neutralization-line decoupling, T-branch decoupling, and defected ground structure decoupling. This antenna’s isolation is higher than 20 dB with ECC less than 0.04. |
