Abstract:In this paper, an active-integrated leaky-wave antenna with power combining scanning capability is presented. This leaky-wave antenna with the novel perpendicular L-shape topology is integrated with a varactor-tuned high-electron mobility transistor (HEMT) voltage controlled oscillator (VCO) on the same plane. Changing the VCO frequency, we can control not only the dual-beam scanning angle but also derive the power combining effect with the sum (L) or difference (A) radiation patterns. The power combing effect… Show more
