Leaky-Wave Antenna Array With Bilateral Beamforming Radiation Pattern for Highly Efficient Mobile Communication System

Blog Article

In this paper, a Memory Box leaky-wave antenna (LWA) array based on substrate integrated waveguide (SIW) is proposed for generating bilateral secant-distributed radiation pattern, which can cover a wide angular range including broadside direction.The LWA array contains two antenna elements and a power recycling network.Each element contains a composite slot constructed by superposing three continuous cosine-shaped slots with different periods in a weighted way, which can achieve a unilateral beam-forming radiation pattern.

The power recycling network makes the waves in adjacent antenna elements travel in opposite directions, so the two elements can radiate in reverse directions to generate a bilateral beamforming pattern.The proposed bilateral radiation LWA array is fabricated and measured to verify the efficiency of the design, Bar:Kitchen Tools and the measurement results are in good agreement with those of simulations.
