Abstract
In this contribution, a planar leaky-wave antenna capable of dual-band frequency scanning including broadside is presented. It is based on the complementary strip-slot element, which is a microstrip-fed slot with ultra broad impedance bandwidth, achieved by introducing its complementary stub on the layer of the microstrip. The mitigation of the broadside degradation is accomplished by properly designing the strip-slot and the pitch of the array and by introducing asymmetry (misalignment) in the unit-cell. The resulting structure differs from previous proposals in the broadband element on which it is based, which allows dual-band behaviour and high efficiency with an array of just five elements.
