Abstract
A novel substrate integrated waveguide (SIW) leaky-wave antenna (LWA) with electronically controlled beam scanning performance is proposed in this paper for microwave and millimeter wave wireless communication systems. By integrating high-band SIW into low-band SIW, a dual-band SIW structure that can transmit Ku-and Ka-band electromagnetic waves can be obtained. Two types of linear slot arrays are etched above SIW for continuous leakage in two bands. In this slot arrays, the radiation state of each slot unit can be controlled by the PIN diodes loaded above it. In this way, different radiation aperture fields can be obtained by controlling the PIN diodes, and the electronically controlled beam scanning of the antenna can be realized. Simulation and measurement verify the feasibility of the design. The measured results show that the antenna can achieve 121° and 81° fixed-frequency beam scanning in Ku and Ka bands, respectively, in the 3dB gain range.
