Abstract
This article proposes model analysis of a microstrip leaky-wave antenna for forward and backward scanning. Mode coupling and dual scan concept is introduced in this article with an inverted V-section leaky-wave antenna. The proposed design concept has been implemented on microstrip planar structure. An inverted V-section has been therefore implemented which resulted in frequency scanning in forward and backward directions in the right-hand (RH) region. The phenomenon has been observed within same frequency bandwidth of leaky-wave region which is normally difficult to see in conventional leaky-wave antennas. The article has also provided a circuit model analysis and design implementation explained by mode coupling theory. The proposed dual scanning leaky-wave antenna (DSLWA) design is providing a wide impedance bandwidth in the Ku-band and K-band with high gain, reduced side lobe levels and high radiation efficiency.
