Since its first introduction about a decade ago, the halfmode substrate-integrated waveguide
(HMSIW) has gained enormous interest from researchers, with particular appeal in the …

A novel slotted substrate integrated waveguide (SIW) leaky-wave antenna is proposed. This
antenna works in the TE 10 mode of the SIW. Leakage is obtained by introducing a periodic …

A comprehensive survey of the reconfigurable leaky-wave antennas (LWAs) is made in this
paper. Beam-steering and unique radiating features of LWA are highlighted particularly …

A simple technique is presented for the complete suppression of the open stopband in
periodic leaky-wave antennas using two similar but nonidentical elements per unit cell. With …

A planar W-band monopulse antenna array is designed based on the substrate integrated
waveguide (SIW) technology. The sum-difference comparator, 16-way divider and 32× 32 …

Significant advances in the development of millimeter-wave and terahertz (30–10 000 GHz)
technologies have been made to cope with the increasing interest in this still not fully …

A planar millimeter-wave 2-D beam-scanning multibeam array antenna fed by compact 16-
way beamforming network (BFN) in multilayered substrate integrated waveguide (SIW) …

A new substrate integrated waveguide (SIW) leaky-wave antenna is investigated for endfire-
radiation with a narrow beam and sidelobe suppression. Maximum directivity conditions for …

Loading effects of radiating discontinuities have been explored to increase the phase
constant'frequency sensitivity of leaky-wave antennas (LWAs), based on which a quasi …

A dual-mode composite microstrip line (DMC-MSL) is reported in this paper for the purpose
of designing dual-band antennas and devices with a large frequency ratio. The metallic strip …
