N2 - This letter presents a wide-angle scanning leaky-wave antenna (LWA) based on composite right-/left-handed metamaterials. The proposed LWA incorporates unit cells with a radiating slot formed by an interdigital capacitor with stepped fingers, interconnected through microstrip delay lines. The innovative radiator design achieves a wide impedance bandwidth of 4 GHz to 6.7 GHz and allows beam steering across a range of −62° to 30°. The antenna demonstrates a peak gain of 10.5 dBi and consistently high radiation efficiency, averaging 72% over the operating range. This high-performance LWA combines a simple design with a compact form factor, offering a cost-effective and easily manufacturable solution. It is specifically optimized for the C-band spectrum and is well-suited for 5G and 6G applications.
