چکیده
|
A lowprofile wideband conical beam antenna which uses two concentric annular ring slots in substrate integrated waveguide (siw) technology is presented. first, a single ring antenna is considered and then the effect of introducing the second slot on bandwidth is investigated and high bandwidth is achieved. a brief parametric study for different slot width is presented. a prototype of the proposed antenna is fabricated and measured. the measured reflection coefficient is in good agreement with simulation. the theoretical result is also provided for s11 to validate the simulation and measurement results. the proposed antenna shows 30% bandwidth in 17 ghz center frequency (|s11

Abstract
|
A lowprofile wideband conical beam antenna which uses two concentric annular ring slots in substrate integrated waveguide (SIW) technology is presented. First, a single ring antenna is considered and then the effect of introducing the second slot on bandwidth is investigated and high bandwidth is achieved. A brief parametric study for different slot width is presented. A prototype of the proposed antenna is fabricated and measured. The measured reflection coefficient is in good agreement with simulation. The theoretical result is also provided for S11 to validate the simulation and measurement results. The proposed antenna shows 30% bandwidth in 17 GHz center frequency (|S11
