An antenna arrangement featuring multiple sub-arrays with different types of antennas (patch, Vivaldi, loop, or cavity-backed) oriented differently between planes, allowing for improved directional characteristics, increased coverage, and reduced energy consumption by enabling flexible alignment and interconnection of antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antennas are arranged on the upper side of the semiconductor chip in the same position as the chip, then the antenna arrangement can be used with different chips, but the area required on the circuit board increases
Solution Approach 1:
The patent transitions from a single-plane antenna arrangement to a multi-plane configuration, stacking antenna elements vertically above the chip. This three-dimensional arrangement allows the antenna system to maintain compatibility with different chips while minimizing the horizontal area occupied on the circuit board, as the additional antenna elements are positioned in the vertical dimension rather than expanding the footprint.
2Adaptability or versatility
If multiple antennas are arranged in the same plane at the same position as the chip, then chip independence is achieved, but the radiation characteristics of the antennas are affected by the chip
Solution Approach 1:
By arranging antenna elements in multiple planes at different heights above the chip surface, the patent reduces the interaction between the chip and the antenna radiation patterns. The vertical separation minimizes the harmful electromagnetic interference while maintaining the chip-independent design, as the antennas are positioned in the vertical dimension away from the chip plane.
3Ease of manufacture
If identical antenna types are used in the antenna arrangement, then manufacturing is simplified, but directional characteristic and antenna gain are limited
Solution Approach 1:
The patent employs different antenna types (such as patch antennas, Vivaldi antennas, or loop antennas) at different positions and planes above the chip. Each antenna type is strategically selected to provide specific radiation patterns and gain characteristics in particular directions. This local differentiation of antenna qualities enables the overall system to achieve superior directional characteristics and antenna gain while maintaining reasonable manufacturing complexity through modular design.

Implementation Method 1
an antenna arranged on the transmitter side, this technical arrangement converts line-bound electromagnetic waves into so-called free-space waves, which propagate from the antenna into space as electromagnetic waves. On the receiver side, the antenna converts the electromagnetic waves arriving as free space waves back into conducted electromagnetic waves
Implementation Method 2
Antennas are required to emit and receive electromagnetic waves
