Description

AN ANTENNA STRUCTURE DEVICE FOR OPTIMIZING A COVERAGE AREA OF A NETWORK TECHNICAE FIELD [001] Embodiments of the present disclosure generally relate to an antenna structure in a cellular network. More particularly, embodiments of the present disclosure relate to an improved and efficient antenna structure device for optimizing a coverage area of a network. BACKGROUND [002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art. [003] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second-generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. The fourthgeneration (3G) technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth-generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth-generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users. [004] Beam steering in the azimuth direction for base station antennas may be implemented in a cellular network. Such beam steering involves physically rotating the antenna using either an external motorized bracket or an internal motor controlled remotely. Such approaches necessitate the use of high torque and wattage motors, gear systems, and electronics enclosed in a bracket with IP65 ingress protection to withstand outdoor weather conditions.
