    Abstract
    A substrate-integrated waveguide (SIW) cavity-backed antenna with two slots on top of the cavity has been proposed in this paper. The bowtie slot is the main radiator of the cavity and a rectangular slot close to the feed point has been etched (to add extra resonance to enhance the bandwidth of the antenna in the desired frequency range). Tuning the rectangular slot improved the fractional bandwidth to 8%. A 7.9 dBi peak gain and a steady beam over the entire bandwidth are achieved. The FTBR (front to back ratio) of the antenna is more than 20 dBi. A standard PCB producing process has been used in order to manufacture the ...

Tuning the rectangular slot improved the fractional bandwidth to 8%. A 7.9 dBi peak gain and a steady beam over the entire bandwidth are achieved. The FTBR (front to back ratio) of the antenna is more than 20 dBi. A standard PCB producing process has been used in order to manufacture the proposed antenna on a single layer substrate.
