Integrated stacked patch antenna array on LTCC material operating at 24 GHz [automotive radar applications]

Analysis of Aperture-Coupled Microstrip Antenna Array on LTCC by FDTD

“…But a disadvantage of planar antenna using LTCC is narrow bandwidth because high dielectric constant. Also the efficiency of the antenna is less by surface wave as increases the height of the substrate [7].…”

Gain-enhanced LTCC system-on-package for automotive UMRR applications

“…This superstrate layer not only enhances the array gain but also adds to the robustness of the design by providing protection against severe conditions. Unlike [9], the design is simple, efficient and cost effective yet provides almost similar performance. The miniaturized module can easily fit into car bumpers or side mirrors etc.…”

“…However, not much work has been done so far on the LTCC based automotive radars. In [9], an LTCC based automotive radar system at 24 GHz has been demonstrated. However, it employs an eight-patch antenna array with a complex feed network, which renders the system to be bulky and inefficient.…”

“…However, it employs an eight-patch antenna array with a complex feed network, which renders the system to be bulky and inefficient. Moreover the design in [9] does not cater for harsh automotive environments.…”

The Application of the FDTD Method to ApertureCoupled Microstrip Antenna Array on LTCC at Millimeter-Wave

“…This technology is mixed small power consumption of the active device component based on the silicon technology and the multi-layer substrate with the low temperature co-fired ceramic (LTCC) [5]. Therefore, this package technology of laminate is used in order to combine the antenna and the ARS into one.…”
