Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna systems struggle to achieve a wide horizontal beam width, which is essential for enhanced coverage in wireless communication environments.
Innovation Solution
The implementation of auxiliary radiating elements that radiate electromagnetic waves substantially antiphase to the main radiating elements, either through 180-degree rotation or phase modulation, to increase the horizontal beam width.

1Length of moving object
If conventional antenna configurations are used, then the antenna structure remains simple, but the horizontal beam width is insufficient for enhanced coverage
Solution Approach 1:
The antenna system is divided into multiple radiating elements (main radiating elements and auxiliary radiating elements) arranged in columns. Each column contains multiple radiating elements that can be independently controlled, allowing the horizontal beam width to be increased by distributing elements across multiple columns while maintaining manageable structural complexity through modular organization.
Solution Approach 2:
The patent transitions from a single-column arrangement to a multi-column arrangement of radiating elements. By adding the column dimension to the vertical arrangement of elements, the system achieves wider horizontal beam width without proportionally increasing overall structural complexity, as elements are organized in a systematic multi-dimensional grid pattern.
2Adaptability or versatility
If auxiliary radiating elements are added to increase horizontal beam width, then coverage is improved, but the antenna system complexity increases
Solution Approach 1:
The auxiliary radiating elements serve multiple functions: they increase horizontal beam width for broader coverage, provide phase diversity through antiphase radiation, and can be integrated into existing antenna arrays without requiring completely separate systems. This multi-functionality improves adaptability while managing the complexity increase.
Solution Approach 2:
Instead of trying to achieve wide coverage with a single conventional element, the patent uses auxiliary elements that radiate in antiphase to main elements. This inverted approach—using opposite phase relationships—creates constructive interference patterns that broaden the horizontal beam width while maintaining controlled system complexity through predictable phase relationships.

AI summary
An antenna includes a first column of main radiating elements, each main radiating element configured to operate in a first operating frequency band and a first auxiliary radiating element. The first auxiliary radiating element is adjacent a first main radiating element in the first column of main radiating elements, and the first auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the first main radiating element.
