Leader-mw | Introduction to Four Element Spiral Antenna Array |
Introducing Leader microwave tech.,(leader-mw) latest innovation in antenna technology - fixed multi-beam helical antenna stereo arrays. This cutting-edge array is designed to revolutionize the way we perceive and use antenna systems, delivering unparalleled performance and versatility in a compact and efficient design.
The heart of this revolutionary array is the helical antenna element, which is carefully integrated into the tapered platform structure. The structure consists of a top surface and multiple sides, each of which is connected to the edge of the top surface. The sides of adjacent sides are also interconnected, creating a seamless and strong platform for the antenna elements.
The unique design of the tapered platform structure allows helical antenna elements to be placed on the top and sides, maximizing array coverage and performance. This configuration enables the array to emit multiple beams in a stereoscopic manner, thereby enhancing the reception and transmission capabilities of the antenna system.
One of the key features of the tapered platform structure is the regular polygonal shape of the top surface, which further enhances the uniform distribution of antenna elements and optimizes the overall performance of the array. This ensures the array can deliver consistent and reliable signal strength across a variety of applications and environments.
