Embodiment 1

[0019] Embodiment 1: 1×16 single polarization broadband phased array antenna based on strong mutual coupling effect

[0020] Reference figure 1 versus figure 2 The first embodiment is composed of two layers of periodic structures printed with octagonal loop elements. Drawing on the naming rules of Yagi antennas, the present invention refers to the lower periodic structure connected by interdigital capacitors at the ends of the elements as the radiating element layer 102, and will be located in the antenna structure The unconnected octagonal loop units at the top are called the guiding unit layer 101, and the strongly mutually coupled broadband phased array with such structural characteristics is called the octagonal loop broadband phased array antenna 100 based on strong capacitive coupling. The space between the radiation unit layer 102 and the guiding unit layer 101 is completely filled with polystyrene foam 107, and the space between the radiation unit layer and the floor is a...

Abstract

The invention discloses an octagonal-ring plane bipolarized broadband phased-array antenna based on strong mutual coupling effects. The antenna comprises a radiation unit layer which is printed on a super-thin medium layer and a guide unit layer; and the radiation unit layer and the guide unit layer are composed of octagonal ring units which are periodically arrayed. The tail ends of the octagonal ring units in the radiation unit layer respectively extend to the tail ends of the adjacent octagonal ring units to form an interdigital capacitor which is capable of enhancing a capacitance coupling amount between the units. The octagonal-ring antenna unit provided by the invention is particularly suitable for the design of a super-broadband bipolarized plane phased-array antenna.

Description

Technical field [0001] The invention belongs to the field of wireless communication, and particularly relates to an ultra-wide bandwidth angular scanning phased array antenna system. Background technique [0002] The antenna system is a device that transmits and receives electromagnetic energy. It is widely used in satellite communications, long-range broadcasting, and military communications systems. The phased array antenna is a well-known form of antenna in the field of antenna research. A phased array antenna usually includes a large number of antenna elements with controllable amplitude and phase, and its radiation pattern is usually determined by the radiation characteristics of a single antenna element, the arrangement of the antenna elements, and the excitation amplitude and phase distribution of the antenna elements. A typical phased array antenna unit usually includes a dipole antenna, a slotted unit, and other antenna unit forms with directional radiation characterist...
