Transverse bow-tie slotted substrate integrated waveguide leaky-wave antenna

A novel bow-tie slotted substrate integrated waveguide (SIW), leaky wave antenna is proposed and investigated. This antenna works in the TE₁₀ mode. Proposed antenna leads to more intense electric field and better coupling of E-field in adjacent slots, which results in more uniform spectral behavior in comparison with transverse slot leaky wave antenna. In addition to this proposed antenna gives improved broad side behavior and can scan larger angular range with in lesser frequency change.
