Microstrip Leaky-Wave Antenna and It's Beam Control Method
Leaky wave antennas are a class of guided wave antennas with broad application pros-pects.Compared with traditional antennas,they have significant advantages and can provide beam control functions for various wireless communication and radar applications.This paper proposes a design and beam control method for leaky wave antennas using capacitive loads to achieve dynamic radiation pattern control.The beam control method is the main focus of the research,which intro-duces capacitive elements at specific locations of the antenna structure to modulate the effective re-fractive index of the guided wave,and achieves beam control by changing the radiation angle of the beam.In addition,the study also analyzes the influence of different parameters of the capacitive load on the radiation characteristics of the leaky wave antenna by changing the parameters of the capaci-tive load.This technology has the characteristics of simple structure,low cost,and easy miniaturiza-tion,and can be integrated into various wireless communication systems and radar arrays..
