AbstractIn this paper, substrate-integrated waveguide (SIW) and half mode substrate integrated waveguide (HM-SIW) periodic leaky wave antennas (LWAs) are presented for the antenna applications. The continuous beam scanning (CBS) is realized by optimizing the unit cell by matching its impedance to the characteristic impedance of the waveguide. This leaky wave antenna is capable of total 60 ° scanning from −38 ° to + 22 ° as the frequency changes from 10.17 GHz to 16.3 GHz with a maximum gain of 11 dBi. Moreover, for further miniaturization, HM-SIW technology is employed in the presented LWA. This LWA is also capable of CBS from −50 ° to + 26 ° in the frequency band of 10 GHz to 16.5 GHz with a maximum gain of 12 dBi. The final prototypes of the both these antenna are fabricated and measured results are in agreement with the simulated ones.
