A compact, low sidelobe level Dolph-Chebyshev array fed by a periodic-stub loaded SW-TL was reported. The antenna exhibits a peak realized gain of 11.8 dBi and has compact transverse dimensions: 3.16 λ0 × 0.6 λ0. Its SLLs are below - 30dB. Other outstanding merits of the prototype array include its broad bandwidth performance, 9.7%, and its low-profile configuration, 0.023λ0.

N2 - A broadband, low sidelobe level (SLL), microstrip array excited with a Dolph-Chebyshev distribution that is implemented with a periodic-stub loaded slow-wave transmission line (SW-TL) feed network is presented. The desired Dolph-Chebyshev excitation of the uniformly spaced microstrip array is achieved simply by modulating the widths of the stubs along the SW-TL feed network. Simulated results demonstrate that the array is low profile, 0.023\lambda_{0} in height, has a broad fractional bandwidth, 9.7%, and exhibits SLLs as low as -30dB.
