Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-polarized antennas with switches are used to support multiple polarizations, then polarization versatility is improved, but signal loss and degradation occur due to switch attenuation
Solution Approach 1:
The patent uses switches to dynamically reconfigure the antenna circuit between single-polarized and dual-polarized modes. The switches enable the antenna to adapt its polarization characteristics based on communication requirements, allowing it to transition from a fixed configuration to a flexible, reconfigurable system that can handle multiple polarizations without continuous signal loss.
2Adaptability or versatility
If multiple antennas with different orientations are used to receive various polarizations, then polarization adaptability is improved, but circuit size and power consumption increase
Solution Approach 1:
The patent combines multiple antenna elements with different orientations into a single integrated antenna structure. Instead of using separate physical antennas for horizontal and vertical polarizations, the invention merges them into one antenna unit that can receive both polarizations simultaneously through its multi-oriented elements, reducing overall circuit size and complexity.
Solution Approach 2:
The antenna unit is designed to perform multiple functions: it can operate in single-polarized mode for basic communication and switch to dual-polarized mode for enhanced polarization adaptability. This universal design allows the same antenna structure to serve different communication requirements without needing separate dedicated antennas for each mode.
3Device complexity
If traditional receiver circuits are used with fixed antenna orientations, then circuit simplicity is maintained, but signal reception quality degrades when polarization mismatches occur
Solution Approach 1:
The receiver circuit incorporates switches that enable dynamic reconfiguration between different reception modes. When polarization mismatch is detected or anticipated, the circuit can switch to dual-polarized reception mode, allowing it to adapt to varying polarization conditions and maintain reliable signal reception without requiring a completely complex restructured circuit.

AI summary
A transceiver circuit that includes multi-port antenna and transmitter and receiver circuit may transmit and receive polarized electromagnetic waves. The polarization of transmitted electromagnetic waves may be determined by adjusting gain and phase differences between multiple circuit paths in the transmitter circuit. In a similar fashion, the gain and phase of circuit paths in the receiver circuit may be adjusted to accommodate different polarizations of received electromagnetic waves.
