Abstract:
A novel pencil-beam, full-space scanning 2D composite
right/left-handed (CRLH) transmission line (TL) leakywave
antenna (LWA) array is proposed. The proposed array
achieves the same performance of conventional phase array
antennas in a simpler manner. Moreover, array elements are
fed by a CRLH infinite-wavelength series power divider and
therefore the separation between array elements and the number
of array element can be extended arbitrary. The CRLH series
power divider eliminates the requirement of complex and high
loss feeding networks commonly found in conventional arrays.
Experimental results of each system components are presented
along with analytical and simulation results of the complete array
system.
Index Terms—Antenna array, composite right/left-handed,
leaky-wave, pencil-beam, frequency-scanning, phase-scanning.
