In this paper a closed-form expression is introduced to calculate slot shape of long slot leaky wave waveguide antennas at its fundamental mode of operation with minimum side lobe level (SLL). The derived equation is a ...

In this article, a new leaky wave antenna (LWA) based on modified substrate integrated

waveguide (SIW) is introduced. At first, the modified SIW structure is

presented and it is shown that it supports propagation of quasi...

In this paper, a new Leaky Wave Antenna (LWA) based on modified substrate integrated waveguide (MSIW) is proposed and investigated. It is shown that MSIW can support the Quasi-TEM mode. Leakage from the antenna is obtained by inter-digital capacitor...

In this paper a new periodic leaky-wave antenna based on substrate integrated waveguide (SIW) is proposed and investigated. The proposed antenna uses multiple transverse slots in the upper plane of the SIW for radiation into the free space...

This paper presents an improved design for waveguide based leaky wave antennas (LWAs) with discrete aperture to achieve a narrow beam and low sidelobe level (SLL). In this design a new formula for calculation of the required leakage constant is used...
