This article examines the issue of extending the inter‐element spacing between slots of equally‐spaced linear grounded frequency selective surface (FSS) arrays with spacing beyond half a wavelength in W‐band (75–110 GHz). We present the design, processing, and testing of W‐band grounded FSS arrays with different inter‐element spacings along transverse electric (TE) and transverse magnetic (TM) field directions separately. The comparison of periodicity changing effects along TE and TM field directions has been reported. The inter‐element spacing versus phase curves demonstrate that in some extent the inter‐element spacing can be a phase optimization parameter for complex array design. We fabricated the corresponding FSS arrays on quartz substrate with photolithographic etching technique, and characterized the vector S‐parameters with a free space MVNA. © 2009 Wiley Periodicals, Inc.
