چکیده
Millimeter-wave (mmWave) antennas are indispensable components in the fifth-generation (5G) wireless communication systems. With inherent advantages of integration capability, substrate integrated waveguide (SIW) antenna is an excellent choice for applications mmWave frequency bands. However, reflection losses occur at dielectric-filled thin apertures SIW antennas. These reflections can be overcome by impedance matching between aperture and free space. In this study, we introduce horn having transitions (IMTs) across horn's width. The designed antenna, operating 24-28 GHz band, simulated with a full-wave analysis tool. simulation results modified have been confirmed experimental shown to satisfactory. IMTs result enhancement front-to-back ratio (FTBR). novel printed transition achieves sidelobe levels (SLLs) better than ?9 dB 27 GHz, enhanced FTBR above 15 dB. 24?28 has coefficient variation ?10

In this paper, a SIW horn antenna is designed using Luneburg lens in order to enhance the gain. Using a transition printed on the same substrate, both the matching performance and the front to back ratio was improved. In addition, this transition structure allows the antenna to be planar. The proposed antenna operates at 14.5 GHz and can be used for Ku band application.An antenna prototype was ...
متن کاملAntipodal Dual Exponentially Tapered Slot Antenna (DETSA) with Stepped Edge Corrugations for Front-to-back Ratio Improvement
We investigate the effect of stepped edge corrugations on the front-to-back ratio (F/B ratio) improvement for the antipodal DETSA. Three types of corrugation configurations with different combinations of slit length are investigated. The results revealed that the improvement in F/B ratio is directly related to the arrangement in corrugation configurations.
