Abstract

A novel design of linear 8-element horn array antenna with 45º-slant polarization operating in octave bandwidth (4…8 GHz) is presented. The array antenna is characterized by sector type radiation patterns with gain ranging from 14 dB (at low frequency) to 18 dB (at high frequency) and side lobe levels less than -12 dB. Wide bandwidth, slant polarization and relatively simple construction were achieved due to the innovative use of combination of E-plane power divider based on rectangular waveguide with symmetrical double-ridged waveguide components. Proposed design was numerically optimized. A prototype has been manufactured, verified and all-round tested.
