Popis:	This paper presents the characteristics of a 6 × 26 slotted waveguide array antenna for a wave monitoring radar system. The proposed antenna was designed as a double-layer structure that operated in the Ku-band and combined the radiating antenna and feeding antenna structures to secure a broad bandwidth. To realize the high-gain properties of the antenna and the beamwidth control, parameters such as the resonance slot length, width, offset, and angle of the feeding slot placed on the broad wall were precisely calculated using the iteration. The measured results for the voltage standing wave ratio, radiation patterns, half-power beamwidth, and peak gains of the 6 × 26 slotted waveguide array antenna agreed well with the simulated results.
