Abstract
A novel negative-resistance composite right/left-handed (NR-CRLH) leaky-wave antenna (LWA) is presented. The conventional CRLH unit cell is made configurable by using the negative resistance (NR) circuit. An LWA constituted by the proposed unit cells allows manipulation of the current distributions over the radiating surface of the antenna. Consequently, the radiation pattern, and directivity can be adjusted to the desired values. The fabricated prototype of the proposed NR-CRLH LWA demonstrates enhanced directivity compared to the conventional all passive CRLH LWA. The proposed method provides simple current amplitude control while minimally influencing the desired dispersive/transmission characteristics of the LWA.
