Design of a Compact 4×4 Ultra-Wideband (UWB) MIMO Antenna with Quadra Band-Notch Characteristics on FR-4 Substrate for Wireless Communication Applications
Muhammad Rhevin Adilla, Annisa Khairani
[Placeholder abstract — replace with real abstract from PDF]. A compact 4×4 UWB MIMO antenna system is designed on a low-cost FR-4 substrate. The design introduces four independent band-notches to suppress interference from existing narrowband services. Measured S-parameters and envelope correlation coefficient are reported and discussed.
