Description
技术领域 technical field
本发明涉及天线，尤其涉及一种牛角弯道形微带天线 。 The present invention relates to antennas, in particular to a microstrip antenna in the shape of a bull-horn curve.
背景技术 Background technique
微带天线是在微带电路出现后发展起来的一种新型天线。从七十年代中期开始，从理论、技术到应用对这种天线进行了大量的研究，至今势头不减。微带天线主要用在微波、毫米波段。在实际应用中，天线的尺寸大小、重量、造价、性能、安装难易和空气动力学形态等都受到限制，这时可能需要低剖面的天线。为满足这些要求，可选用微带天线。这种天线有薄的平面结构，便于共形，制造简单，成本低。通过选择特定的贴片形状和馈电方式可以获得所需的谐振频率、极化、模式、阻抗。同时可以通过在贴片和介质基片间加负载调整谐振频率、极化、模式、阻抗等各参量。 The microstrip antenna is a new type of antenna developed after the appearance of the microstrip circuit. Since the mid-1970s, a lot of research on this kind of antenna has been carried out from theory, technology to application, and the momentum has not diminished so far. Microstrip antennas are mainly used in microwave and millimeter wave bands. In practical applications, the size, weight, cost, performance, ease of installation, and aerodynamic shape of the antenna are all limited, and a low-profile antenna may be required at this time. To meet these requirements, microstrip antennas can be used. This antenna has a thin planar structure, which facilitates conformality, simple fabrication, and low cost. The desired resonant frequency, polarization, mode, and impedance can be obtained by selecting a specific patch shape and feeding method. At the same time, various parameters such as resonance frequency, polarization, mode, and impedance can be adjusted by adding a load between the patch and the dielectric substrate.
随着微波集成技术的发展和空间技术对低剖面天线的迫切需求，国际上展开了对微带天线广泛而深入地研究。此外，近代通信技术发展迅速，所需传输速率越来越高，带宽也越来越宽。超宽带通信技术以高速、安全、容量大、抗多径等其他窄带通信系统所不具备的优点受到广泛关注。宽频带、新结构和高性能的微带天线不断涌现。超宽带微带天线具有较大的频带范围，可以满足各个频段的需求。因此，迫切需要研究出尺寸小型，频带范围宽，辐射特性好的微带贴片天线。 With the development of microwave integration technology and the urgent need for low-profile antennas in space technology, extensive and in-depth research on microstrip antennas has been carried out internationally. In addition, with the rapid development of modern communication technology, the required transmission rate is getting higher and higher, and the bandwidth is getting wider and wider. Ultra-wideband communication technology has attracted widespread attention due to its high speed, security, large capacity, anti-multipath and other advantages that other narrowband communication systems do not have. Broadband, new structures and high-performance microstrip antennas are emerging. The ultra-wideband microstrip antenna has a large frequency band range, which can meet the needs of various frequency bands. Therefore, it is urgent to develop microstrip patch antennas with small size, wide frequency range and good radiation characteristics.
