3D metal printed slot antenna array with high gain and enhanced bandwidth using triple-mode sine corrugated cavity resonator
This letter proposes a class of sine corrugated cavity resonators (SCCR). The SCCR can present slow-wave features and provide dual-mode (TE104 and TE105) wideband responses with reasonable sine period and depth. Based on it, a compact high-gain bandwidth-enhanced SCCR slot antenna array is designed. The high gain is obtained with seven radiation slots and the wideband is achieved due to three modes being utilised. The three modes include the modes of TE104 and TE105 of the SCCR and one feed slot mode. Compared with published works, the desired TE104 and TE105 can be obtained straightforwardly based on SCCR. The standard WR62 waveguide is utilised to feed the antenna. For validation, direct metal 3D printing technology is used to fabricate it with aluminium and copper powders as a comparison. Both measured results were discussed and showed a good agreement with the simulated ones.
