AbstractIn this paper, the scanning rate (SR) is enhanced for substrate integrated waveguide (SIW) based periodic leaky wave antenna (LWA) with continuous beam scanning. Delay line is inserted in the SIW based periodic LWA to modify the group delay profile which in turn increase the SR of the SIW based periodic LWA. Addition of the delay line enhances the SR of the SIW LWA to approximately three times from 15.6° to 47° per GHz. The prototype of the proposed LWA is fabricated and experimentally measured. The simulated and measured results show that the proposed LWA scans the angular range from −30° to +27° within a frequency span of only 1.2 GHz from 14.8 to 16 GHz (relative bandwidth of 7.7 %).
