Solution Overview
Problem
Current wireless communication systems face challenges in integrating efficient antenna structures within the limited space of integrated circuits (ICs), as traditional three-dimensional antennas cannot be implemented in two-dimensional IC or printed circuit board (PCB) spaces, and two-dimensional antennas are too large to fit on-chip due to size constraints.
Innovation Solution
The development of an integrated circuit (IC) antenna structure that includes a plurality of antenna structures on the die and/or package substrate, utilizing electromagnetic properties to operate within specific frequency bands, such as 55 GHz to 64 GHz, allowing for local and remote wireless communications without the need for conductive traces between ICs, enabling efficient signal transmission and reception.

Engineering Contradiction Analysis
1Reliability
If traditional three-dimensional antennas are used, then antenna efficiency is improved, but device area increases making them incompatible with two-dimensional IC spaces
Solution Approach 1:
The patent transitions from three-dimensional antenna structures to two-dimensional planar antenna structures that can be integrated on IC chips. The antenna elements are arranged in a planar configuration on the IC surface, enabling efficient wireless communication while conforming to the two-dimensional constraints of integrated circuit packaging.
2Area of stationary object
If two-dimensional antennas are used to fit IC space, then device area is reduced, but antenna efficiency deteriorates due to size constraints
Solution Approach 1:
The patent divides the antenna system into multiple discrete antenna elements that are segmented and distributed across the IC surface. This segmentation allows the total antenna area to be distributed in a way that maintains radiation efficiency while fitting within the limited IC footprint. The multiple elements can work together to provide enhanced performance.
Solution Approach 2:
The patent incorporates switching circuitry that dynamically selects and activates different antenna elements based on communication requirements. This dynamic configuration allows the antenna system to adapt its effective area and radiation pattern, maintaining efficiency across different operating conditions despite the constrained two-dimensional space.
