Four-element triple-band systems have been studied and developed for
long-term evolution
(LTE) and 5G mid-band (4.5–4.9 GHz) operation. The presented multi-input multioutput (MIMO) consists of four planar which are excited with inset feeding. The system is designed on substrate (FR-4) with dielectric constant (
ε
r
) of 4.4 and dielectric loss (tan
δ
) 00.02. The complete measurements of implemented antenna are 150 × 150 × 1.6 mm

|≤ − 10 dB. This antenna is operating for LTE band 40 (2300–2400 MHz) at 2.4 GHz with impedance bandwidth of 58.6 MHz, LTEA band 46 (3700–4000 MHz) at 3.7 GHz with operating bandwidth of 87.1 MHz and 5G mid-band range for Japan (4500–4900 MHz) at 4.5 GHz with operating bandwidth 87.1 MHz. This MIMO provides > 21 dB isolation among the 4 elements operating under the operating band. Therefore, the antenna is appropriate for LTE/5G operations.
