English Abstract

This paper presents a dual-port antenna system that combines the features of both cognitive radio and MIMO diversity.

The system is designed on a compact size 90×70×1.6 〖mm〗^3 FR4 substrate with PIN diodes integrated within feed line to achieve frequency reconfigurability.

The proposed design can be switched between a Wide Band (WB) sensing mode (2.24-4.5 GHz) and four communication modes that serve WiMax, Wi-Fi and C-band applications.

A single-band (3.2-3.72 GHz) and dual-band (2.28-2.46 GHz /3.85-4.2 GHz) with their MIMO duplicates are accessible in communication modes of operation.

The proposed antenna system is designed using CST full-wave modeling under realistic electromagnetic effects and its feasibility as a cognitive radio system is verified by highly acceptable results regarding S-parameters, realized gain and impedance matching.

System's reliability as a MIMO system is ensured by envelope correlation coefficient, diversity gain and mutual coupling fairly good results.

All outcomes confirm that the proposed system looks promising as a MIMO cognitive radio This paper presents a dual-port antenna system that combines the features of both cognitive radio and MIMO diversity.
