A Dual-Band Compact Antenna Array with Scattering Suppression Capability in Low Band

A new compact antenna with scattering suppression effects and operating in low band (LB) of 1.71 to 2.21 GHz is presented in this paper. Thanks to the effects, four very small-distance antennas operated in high band (HB, 3.3–3.6 GHz) are successfully interleaved with above one LB antenna, enabling our new dual-band compact antenna solutions..Simulated results shown that the antenna, with higher than 10dB of return loss in both band and 6.5dB/9.5dB of realized gain in LB/HB, has very promising for 5G applications.
