Design and experimental analysis of asymmetric fed key-shaped eight-port flexible frequency diversity MIMO antenna with multi-band applications
In this communication, Key-shaped asymmetric-feedline eight-port MIMO antenna is reported which is designed on thin Rogers substrate for flexible-applications. A Key-type slotted-radiating patch printed on top-surface with slotted half-electrical ground achieves super wideband measured bandwidth of 7.50 GHz to > 80.0 GHz. The additional rectangular-strip attached to the ground which is the added feature generates narrow-band of measured-bandwidth 3.37–3.65 GHz. The single-port antenna is printed with antenna size of 14 × 14 mm2 and the narrow-band is useful for WiMAX wireless communication & n48/n77/n78 Sub-6.0 GHz 5G-bands, while super wideband applications include X-band satellite communication, Ku-band RADAR with millimetre bands integrating ISM 24.0 GHz, UWB- 24.0 GHz, 5G—mm Wave communication (n257, n258, n259, n260, n261, n262, n263). The time-domain response including impulse response and group delay shows very low ringing and vibration of 1.0 ns. The single-port, four-port and eight-port MIMO antenna is studied for bending at 45° with minimal deviation of −10 dB bandwidth. The diversity parameter ECC < 0.05 (Band 1 and Band 2), DG dB (Band 1 and Band 2), TARC < −10.0 dB (Band 1 and Band 2) and CCL < 0.2 b/s/Hz in both the bands. The maximum measured peak gain is 7.72 dBi with efficiency more than 79.69%. The acceptable radiating-pattern with overall size of 16,000 mm2 is well suited for wireless-applications in multiple-bands.
