Null-steering in two-element time modulated linear antenna array through pulse-delay approach

This paper presents results of investigation on the radiation pattern generated with two-element Time Modulated Linear Array with single SP4T microwave switch. Utilization of SP4T switch instead of multiple SPST switches reduced an amount of power dissipated in matched loads and increased total efficiency. Due to the pulse-delay approach the null of radiation pattern has been continuously steered in a wide range of angles.
