Abstract EN
In order to facilitate the integration of active devices, a leaky-wave antenna (LWA) based on corrugated substrate integrated waveguide (CSIW) structure is proposed.
By introducing rectangular ring slots on the CSIW structure, the proposed LWA is capable of beam scanning from backward to forward.
The rectangular ring slots do not only enable energy leaking but also provide series capacitance.
In addition, the grounded vias and quarter-wave open-circuit stubs provide shunt inductance.
Thus, the proposed CSIW exhibits left-handed characteristic which enables beam scanning through the broadside.
To further facilitate the design and suppress open-stopband of beam scanning antenna based on CSIW structure, an equivalent circuit model is developed and the relationships between structure parameters and the equivalent circuit parameters are presented.
Based on this design guide, a leaky wave antenna is designed with radiation angle ranging from −53° to 23°.
This proposed novel CSIW LWA has great potential in tunable or reconfigurable antenna design due to its ease of integration with active devices.
