Composite right/left-handed (CRLH) resonant antennas (RAs) have been less studied than their leaky-wave antennas (LWAs) counterpart. However, they exhibit equally interesting features, which are in fact complementary to those of LWAs. This paper presents an overview of recent works on CRLH RAs, in comparison with CRLH LWAs.
