Abstract:

Leaky-wave antennas (LWAs) have the ability to scan beam with frequency. However, the major limitation faced by most of the LWAs, particularly uniform LWAs, is their inability to scan beam through broadside. A method to achieve a continuous beam scan from backward to forward is discussed here. A substrate-integrated waveguide (SIW)-based structure is used for the study. The SIW-based LWA with only horizontal (longitudinal) slots is unable to scan the beam through the broadside due to an open stopband (OSB). The OSB is closed by using additional vertical (transverse) slots and groups of shorting vias. The simulated results show that the LWA can scan beam continuously from -47 to +27when frequency sweeps from 8.75 to 13 GHz.
