A planar array design is commonly carried out by applying an optimal linear array design [1]. The utilization of power weighted method based on some functions such as binomial, Chebyshev, or Kaiser function, is sometimes helpful achieving the desirable array performances, in particular to satisfy specific radiation characteristics. In this work, the design of S-band planar array using power-weighted method based on Kaiser function is presented. The design which takes a 4\mathrm{x}8 planar array with uniform-Kaiser weighted combination is developed from the previous experimental work on a 1x4 Kaiser-based linear array [2]. The proposed planar array is configured as many as 4 set in a uniform distribution for a 1x8 Kaiser-based linear array with similar distance between adjacent patches either towards the x-axis or the y-axis. The coefficients set of Kaiser function with \beta value based on targeted sidelobe level (SLL) is determined using formulas in [3]-[4]. As illustrated in Figure 1(a), an S-band planar array which is fed by proximity coupled feeding techniques uses two-layers of FR4 epoxy dielectric substrate for the design, in which each layer has the thickness of 1.6 mm.
