Dual-Polarization Dipole Antenna With Arc Wires for Coverage Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-polarized antennas often suffer from insufficient polarization coverage, leading to vertically polarized zero-coverage areas that limit signal reception.
Innovation Solution
A dual polarization antenna device is designed with multiple arc wires and input terminals configured to transmit and receive signals in orthogonal directions, ensuring comprehensive polarization coverage by intersecting tangent lines at specific angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-polarized antenna is used, then the structure is simple, but the polarization coverage is insufficient with vertically polarized zero-coverage areas
Solution Approach 1:
The antenna is divided into multiple arc wires (first, second, third, and fourth arc wires) with different orientations. Each arc wire handles a specific polarization direction, collectively providing full polarization coverage. The front arc wires (first and second) and rear arc wires (third and fourth) are segmented to cover different spatial directions.
Solution Approach 2:
The antenna transitions from a single-polarization (one-dimensional) structure to a dual-polarization (two-dimensional) structure by adding arc wires in orthogonal directions. The tangent lines of the arc wires intersect at angles, creating coverage in multiple polarization dimensions simultaneously.
2Adaptability or versatility
If multiple arc wires are added to achieve dual polarization, then the polarization coverage is improved, but the device complexity increases
Solution Approach 1:
Multiple arc wires are merged into a single integrated antenna structure sharing common input terminals. The first and second arc wires are coupled to the first input terminal, while the third and fourth arc wires are coupled to the second input terminal, combining multiple functions into unified structures.
Solution Approach 2:
Each arc wire serves multiple functions: transmitting signals in specific directions, receiving signals from corresponding directions, and contributing to overall polarization coverage. The arc wires are designed to handle both transmission and reception, making them multi-functional elements.

AI summary
A dual polarization antenna device includes a first input terminal, a first arc wire, a second arc wire, a third arc wire, and a fourth arc wire. A first terminal of the first arc wire transmits and receives an output data signal along a first direction. A second terminal of the second arc wire transmits and receives the output data signal along a second direction. The first input terminal forms a first tangent line along the first arc wire, the first input terminal forms a second tangent line along the second arc wire, and the first tangent line and the second tangent line intersect each other at an angle. A third terminal of the third arc wire transmits and receives the output data signal along a third direction. A fourth terminal of the fourth arc wire transmits and receives the output data signal along a fourth direction.
