Abstract

The invention discloses a miniaturized cylindrical conformal microstrip array antenna. The miniaturized cylindrical conformal microstrip array antenna comprises a metal cylindrical conformal body (1),a rectangular dielectric substrate (2) and a metal reflection grounding layer (3) fully attached to the lower surface of the dielectric substrate (2), wherein the dielectric substrate (2) is bent tobe on the outer surface of the metal cylindrical conformal body (1) in a conformal mode in the length direction; even number of E-shaped metal matching units (41, 42 until 438) are uniformly distributed on the upper surface of the dielectric substrate (2) along the circumferential direction of the metal cylindrical conformal body (1); and the antenna also comprises a feeding network which consistsof a feeding port (8), microstrip matching lines (5, 7) and a microstrip connecting line (6). The miniaturized cylindrical conformal microstrip array antenna is small in size, simple and compact in structure and high in gain.

Description

technical field [0001] The invention belongs to the technical field of millimeter-wave conformal microstrip antennas, in particular to a miniaturized cylindrical conformal microstrip array antenna with compact structure, small volume and high gain. Background technique [0002] Microstrip antennas are small in size and low in profile, making them easy to conform to the carrier. [0003] When the traditional classic antenna matches the carrier, its antenna performance will change greatly. It can be seen that the requirements for conformal antenna design are higher, not only requiring the antenna to meet electrical performance indicators, but also requiring the antenna to be consistent with the carrier in a special application environment. The conformal array antenna means that the array antenna is attached to the surface of the carrier and bonded to the carrier to form a non-planar conformal array antenna. Microstrip conformal array antennas have become one of the current r...
