In the rapidly developing communication technology, microwave millimeter wave products, as an important part of modern wireless communication systems, play an increasingly critical role. These passive antennas and devices working in the 4-86GHz frequency band can not only achieve high dynamic range and broadband signal transmission, but also provide efficient communication links without the need for power modules, becoming an indispensable element in point-to-point wireless communication systems.
Technical characteristics of microwave antennas and devices
To understand microwave products, you first need to master their basic terms and performance indicators. For wireless communication systems, the performance of antennas and devices directly affects gain, efficiency, link interference and service life. As the key to energy conversion, the radiation characteristics of antennas are particularly important, and the loss, isolation and other indicators of microwave devices should not be ignored when selecting. These performance indicators jointly determine the overall effectiveness of the antenna feed system and affect parameters such as gain, directional pattern, and cross-polarization.
With the development of technology, traditional microwave antennas are gradually developing in the direction of broadband and high efficiency. Many companies have launched broadband antennas that meet the needs of larger bandwidths, such as the 20% broadband antenna launched by Tongyu Communications. On the other hand, the diversification of polarization modes also provides the possibility for improving system capacity. Dual-polarized microwave antennas have been widely used in XPIC microwave communication systems.
Application scenarios of microwave antennas and devices
Microwave antennas have a wide range of application scenarios, which can be mainly divided into electrical scenarios and environmental scenarios. Electrical scenarios focus on the construction of radio links, including point-to-point (p2p) and point-to-multipoint (p2mp). Different types of antennas have different requirements for radiation characteristics. Environmental scenarios focus on coping with specific environmental challenges, such as highly corrosive seaside or hurricane-prone areas, which require corrosion-resistant and wind-resistant antennas.
In microwave link communication systems, the matching of antennas and active wireless transmitters and receivers is crucial. Antenna manufacturers usually provide specific connectors or antenna matching transition units to ensure that their products are compatible with radio equipment from different manufacturers, thereby improving the adaptability of products and providing users with more choices.
Future development direction
Looking to the future, microwave millimeter wave antennas and devices will develop in the direction of high performance, low cost, multi-polarization, broadband, high efficiency, miniaturization, customized integration and high frequency. With the popularization of LTE systems and future 5G networks, small base station systems will become more common, placing higher requirements on the number and performance of microwave links. In order to meet the growing system bandwidth requirements, multi-polarization, broadband and high-frequency technologies will be further promoted. At the same time, the miniaturization and customized integration of antenna systems will become the future development trend to adapt to the reduction of system volume and the growth of personalized needs.
As the cornerstone of modern wireless communication systems, microwave millimeter wave antennas and devices will play a more important role in the future with the continuous development of technology and the continuous expansion of the market.
