A reference SIWLSAA used for comparison purpose comprises of 3×6 slotted arrays constructed on the top and bottom sides of the FR-4 lossy substrate has maximum isolation of -63 dB between its radiation slots. Improvement in isolation is demonstrated using a simple new technique based on inserting a metal fence between each row of slot arrays. The resulting isolation is shown to be is better than -83 dB across 200 MHz to 1.0 GHz with gain greater than 1.5 dBi, and side-lobe level less than - 40 dB. The proposed SIWLSAA is compact and has dimensions of 40×10×5 mm 3 (0.026?×0.006?×0.0020) where ? is 200 MHz. The proposed structure should find application in multiple-input multiple-output (MIMO) and radar systems.4 p.application/pdfeng© 2018 IEICE. Personal use of this material is permitted.
