Abstract :
A single-layer corporate-fed slot array using hollow rectangular coaxial lines is presented. A 16×16-element array is designed and analyzed. For the wideband operation, a cavity-backed wide slot is adopted as a radiation element. The 5.7% bandwidth for the reflection less than -14 dB is obtained by simulation. The antenna efficiency of 68.1% is achieved with the gain of 32.1 dBi including the losses at 61.5 GHz. The conductor loss in the array is 0.6 dB.
