PROJECT TITLE :

A Planar Dual-Band Periodic Leaky-Wave Antenna Based on a Mu-Negative (MNG) Transmission Line

ABSTRACT:

In this study, a planar periodic leaky-wave antenna (LWA) that has a dual-band full-space scanning property is presented. The LWA is based on a mu-negative (MNG) transmission line that offers a nonlinear dispersion characteristic with a terribly straightforward structure. The dual-band beam scanning property is achieved by utilizing the and space harmonics to beat the limitation of the MNG line that gives forward scanning solely within the area harmonic. Microstrip bends are introduced to achieve proper matching and thereby suppress the open stopband result at each broadside radiation frequencies, to avoid interference between two house harmonics, and to make sure efficient radiation. The proposed style method is validated by sensible agreement between the simulated and experimental results for the twin-band LWA that's designed to produce full-space scanning with the primary and second broadside radiation frequencies at four.3 and eight GHz. The demonstrated total scan angle vary of 279° is that the widest vary reported for the dual-band LWA.
