Abstract:
A wideband leaky-wave antenna (LWA) is
designed using composite right/left-handed (CRLH) T-shaped
slotted unit cells integrated with a substrate integrated waveguide
(SIW). The antenna features a multilayered structure, with a
parasitic rectangular patch layer sandwiched between two
substrate layers. The proposed antenna consists of twenty-one T
shaped slotted CRLH unit cells, enabling continuous beam
steering through frequency sweeping. The antenna beam can be
steered across a range of angles such as -53° to 64°, within a
frequency range from 5.48 GHz to 8.215 GHz and antenna design
achieves a peak gain of 9 dBi. The proposed antenna is well-suited
for cost-effective beam scanning applications.
