A SIW based leaky-wave antenna for 5 GHz narrowbeam applications

A substrate integrated waveguide (SIW) based leaky wave antenna (LWA) with narrow beamwidth, low side lobe levels and high directivity is proposed. The desired radiation characteristics are attained by periodic arrangement of a group of slots whose lengths follow the binomial distribution. Without t...

Summary:A substrate integrated waveguide (SIW) based leaky wave antenna (LWA) with narrow beamwidth, low side lobe levels and high directivity is proposed. The desired radiation characteristics are attained by periodic arrangement of a group of slots whose lengths follow the binomial distribution. Without the need for any complex feeding structure, the antenna exhibits a beamwidth of 11.3° and sidelobe level (SLL) <; -10 dB at 5.6 GHz. Designed on an Rogers Duroid 5880 substrate, the antenna's size is 250×45 mm 2 . Achieving a good match between simulated and measured results, the proposed antenna can be used in applications requiring narrowbeam patterns in the 5 GHz band.
