Abstract

A planar slot antenna array operating at 140-GHz band is presented and implemented using a low-temperature co-fired ceramic (LTCC) process. The array comprises a substrate integrated waveguide (SIW) feeding network and slot radiators with a dielectric loading. Considerations associated with the 140-GHz design and the effects of the dielectric loading on antenna performance are investigated. Measured results show that the boresight gain of a 4 × 4 antenna array including a transition from SIW to a waveguide is 16.3 dBi at 140 GHz and higher than 13.8 dBi over the operating bandwidth of 130-152 GHz. Therefore, the LTCC process offers one more option of planar broadband antenna array designs operating at upper millimeter wave bands.
