A frequency reconfigurable antenna based on substrate integrated waveguide (SIW) technology is proposed in this paper for K/Ku band applications. In most of the previous structures terminal SIW was used but here structure, as well blind vias being implanted to achieve maximum reconfigurability and better efficiency miniature antenna. The parameters are analysed thoroughly without diode with dio...

In this research work, a multibeam antenna which is a combination of a beamformer network (BFN) and a linear array antenna, has been designed. A Rotman lens has been chosen as beamformer network and Vivaldi antennas have been selected for constructing array antenna. The Substrate Integrated Waveguide (SIW) was used for implementing Rotman lens. After explanation the structure of Substrate integ...

This letter presents a substrate-integrated waveguide (SIW) antenna for CubeSat applications. The compact structure utilizes middle-point feeding and shorting walls to achieve broadside radiation in the far-field at two distinct frequencies. In particular, this dual-frequency behavior is related transition from dominant leaky wave (LW) on aperture lower frequencies more hybrid (at higher freque...
