Patent ID: 11837791

Abstract:
A microstrip antenna array including: a thin substrate; two or more microstrip radiating patches placed on a first side of the substrate, each radiating patch including: an input port; a radiating patch width (WRP) extending in a longitudinal direction; a radiating patch length (LRP) extending in a transverse direction, wherein the transverse direction is perpendicular to the longitudinal direction, and wherein the longitudinal and transverse directions are in the plane of the radiating patch; a radiating patch transverse axis (TRP) along the midpoint of the radiating patch width; and a radiating patch longitudinal axis along the midpoint of the radiating patch length, wherein the two or more radiating patches are spaced in the longitudinal direction such that the radiating patch longitudinal axis of each radiating patch is aligned along a common longitudinal axis (C); and one or more parasitic patches placed on the first side of the substrate.
