Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are used to support multiple frequency bands, then the coverage of different frequency bands is improved, but the device complexity and structural costs increase
Solution Approach 1:
The patent combines multiple frequency band transmission functions into a single antenna structure. The antenna element is designed with multiple ports, where each port can transmit signals for different frequency bands. This merging approach eliminates the need for separate antennas for each frequency band, thereby reducing device complexity and structural costs while maintaining multi-band coverage capability
Solution Approach 2:
The antenna element is designed as a universal structure that can handle multiple frequency bands through its multiple ports. Each port is configured to transmit specific frequency bands, allowing the single antenna to perform multiple functions (transmitting different frequency bands) simultaneously, thus improving adaptability without increasing overall system complexity
2Adaptability or versatility
If multiple antennas are deployed for different frequency bands, then the transmission capability across bands is improved, but the installation complexity increases
Solution Approach 1:
By merging multiple frequency band transmission capabilities into a single antenna structure with multiple ports, the installation process is simplified. Instead of installing and configuring multiple separate antennas, the system requires installation of only one antenna unit, significantly reducing installation complexity while maintaining the ability to transmit across multiple frequency bands
3Adaptability or versatility
If multiple antennas are used for different frequency bands, then the frequency band coverage is improved, but the structural costs increase
Solution Approach 1:
The patent merges the functionality of multiple antennas into a single antenna structure. By using one antenna with multiple ports instead of multiple separate antennas, the quantity of physical antenna units is reduced, thereby decreasing structural costs while maintaining comprehensive frequency band coverage through the multi-port configuration

AI summary
The technology disclosed herein relates to a modular antenna (a single multi-band antenna system) having various sets of antenna elements for transmitting a plurality of frequency bands. In some embodiments, the sets of antenna elements can be configured vertically in a column based on the frequency band (e.g., a first vertical column for low-band frequencies, a second vertical column for high-band frequencies, and third vertical column for millimeter wave frequencies). In other embodiments, the antenna elements that transmit longer wavelengths can be positioned around the antenna elements that transmit shorter wavelengths. Each portion of the modular antenna that includes a particular set of antenna elements corresponding to a particular frequency range can each have an individual dedicated reflector and separate printed circuit board. Further, each of the antenna elements of the modular antenna can have the same gain.
