摘要: Abstract In this paper, a compact coplanar waveguide (CPW)-fed quasi-elliptical-self-complementary antenna (QESCA) exhibiting super-wideband (SWB) characteristics with dual-band notches for four-port multiple-input-multiple-output (MIMO) systems is presented. order to achieve better inter-element isolation and polarization diversity, the four radiating elements of MIMO are placed orthogonal each other. Each element has an elliptical shape conductor patch slot, which complement similar shape, both present on same side substrate. At port, proposed shows excellent SWB (1.25–40 GHz), providing bandwidth ratio 32:1. Further, two independent slits loaded reject Wi-MAX (3.5 GHz) WLAN (5.5 GHz) bands from SWB. Inter-element more than 18 dB up 15 GHz over 25 dB in higher frequency range obtained. Measured parameters fabricated prototype good agreement simulated results.
