Core structures (120) for composite panels (75) of an aircraft (10), composite panels (75) and aircraft (10) including the core structures (120), and methods (200) of manufacturing the composite panels (75) are disclosed herein. The core structures (120) include a first side (140), a second side (150), and a connecting region (160) that interconnects an upper portion (142) of the first side (140) with an upper portion (152) of the second side (150). The first side (140), the second side (150), and the connecting region (160) at least partially define an antenna housing (62), which defines a housing volume (64) configured to contain an aircraft antenna (60) of the aircraft (10), and an electromagnetic wave transmission region (66) configured to permit electromagnetic waves to pass therethrough. The electromagnetic wave transmission region (66) defines a plurality of kite-shaped voids (130) arranged in a repeating pattern and bounded by a corresponding plurality of walls (170), at least 10% of which extends at least substantially perpendicular to a surface (122/124) that bounds the electromagnetic wave transmission region (66).
