本文讨论了几种新型的复合左右手漏波天线。在这四种情况下，结构的左手和右手性质都允许设计者实现非凡的现象。第一天线是CRLH LW天线，其可以通过使用变容二极管在固定频率下进行波束宽度控制而沿着进行辐射角扫描。第二个天线是LW阵列天线，可以执行2-D频率控制波束转向。接下来，我们讨论一种共模/差模LW天线，其可以在差模操作下以左手（LH）模式操作。另一方面，该天线的共模处于截止区，这使得它非常适合于集成混频器应用。下一个结构是共形CRLH LW天线，其已经被色散工程化以在辐射波束宽度方面执行与平面版本类似的辐射特性。最后讨论了两种有源CRLH长波天线，一种用于波束赋形，另一种是集成了分布式放大器的CRLH长波天线。
In this paper several novel composite right/left-handed (CRLH) leaky-wave (LW) antennas are discussed. In each of the four cases both left-handed and right-handed properties of the structure allow the designers to achieve extraordinary phenomena. The first antenna is a CRLH LW antenna that can perform radiation angle scanning along with beamwidth controlling at a fixed frequency by using varactor diodes. The second antenna is a LW array antenna that can perform 2-D frequency-controlled beam-steering. Next, we discuss a common-/differential-mode LW antenna which can operate in a left-handed (LH) mode under differential-mode operation. On the other hand, the common-mode is in the cut-off region of this antenna which makes it well suitable for integrated mixer application. The next structure is a conformal CRLH LW antenna that has been dispersion engineered to perform similar radiation characteristics as a planar version in terms of the radiation beamwidth. Finally we discuss two active CRLH LW antennas, one is used for beam-shaping and the there one is a integrated CRLH LW antenna with distributed amplifier (DA).
