SITUATION
Four-Port MIMO Antenna
Compact multiport antenna systems for sub-6 GHz wireless applications must provide sufficient bandwidth and isolation while retaining acceptable gain, efficiency and diversity performance.
WHAT I DID
Design and Evaluation
Designed and evaluated a compact four-port flower-shaped MIMO antenna using orthogonal element placement and a microstrip-based decoupling approach. Performance was assessed using impedance bandwidth, isolation, gain, radiation efficiency, ECC and diversity gain.
RESULT
Results and Suitability
The developed configuration achieved wide sub-6 GHz operation with isolation exceeding 20 dB and strong diversity characteristics, demonstrating suitability for wireless access and IoT gateway applications.
Bandwidth
Wide impedance bandwidth across the sub-6 GHz band from a compact four-port flower-shaped layout.
Isolation
Isolation exceeding 20 dB, achieved through orthogonal element placement and a microstrip-based decoupling approach.
Diversity
Strong diversity characteristics assessed through gain, radiation efficiency, ECC and diversity gain.
