Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chip antenna measurement systems are limited in their ability to measure radiation patterns on all three planes (x-z, y-z, and x-y) due to structural constraints, only allowing for partial pattern measurement on specific planes.
Innovation Solution
A high-frequency chip antenna measurement system comprising a platform with two piers, a semicircular arching, a stepper motor, an indication and fastening assembly, a carrier stage, a chip antenna carrier, a probe carrier, and a bridging member, which allows for pivoting of the arching to enable measurement on all three planes by adjusting the position of the source antenna and probe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional measurement platform with a fixed source antenna and single-plane rotation is used, then the device complexity is reduced, but the measurement capability is limited to only one or two planes (cannot measure all three planes x-y, x-z, and y-z)
Solution Approach 1:
The measurement system is divided into three independent rotation mechanisms: a first rotation mechanism for rotating the source antenna holder around the z-axis, a second rotation mechanism for rotating the probe carrier around the x-axis, and a third rotation mechanism for rotating the probe carrier around the y-axis. This segmentation allows each mechanism to handle one specific plane measurement, enabling comprehensive three-plane measurement capability while keeping individual mechanisms relatively simple.
Solution Approach 2:
The probe carrier is designed with dual rotation capabilities (around x-axis and y-axis), allowing it to perform multiple functions: measuring patterns on the x-z plane when rotating around the x-axis, and measuring patterns on the y-z plane when rotating around the y-axis. The source antenna holder can also measure on the x-y plane when rotating around the z-axis, making the system universally capable of measuring all three planes.
2Ease of operation
If a semicircular arching structure with manual or motor-driven rotation is used, then angle switchover for different measurement angles is enabled, but the measurement is still restricted to only upper-half patterns on specific planes
Solution Approach 1:
The system employs three dynamic rotation mechanisms with adjustable ranges: the source antenna holder can rotate around the z-axis, and the probe carrier can independently rotate around the x-axis and y-axis. These dynamic adjustments enable the system to access different measurement planes and achieve complete spherical coverage, overcoming the static limitation of conventional semicircular arching structures that only provide upper-half pattern measurement.
3Reliability
If the source antenna and probe are connected via high-frequency coaxial cable, then electromagnetic energy transmission is achieved, but the system cannot measure radiation patterns on all three planes due to structural constraints
Solution Approach 1:
The system transitions from conventional two-dimensional measurement (single plane or limited planes) to three-dimensional measurement by adding rotational degrees of freedom. The source antenna holder rotates around the z-axis to enable x-y plane measurement, while the probe carrier rotates around both x-axis and y-axis to enable x-z and y-z plane measurements respectively, achieving complete three-dimensional radiation pattern characterization.
