Embodiment 1

[0019] Embodiment 1: As shown in the figure, a series-fed planar printed array antenna includes an upper dielectric board 1, a lower dielectric board 2, a microstrip radiation group, a metal ground layer 3 and a microstrip feeder 4, the upper dielectric board 1, The lower dielectric board 2 and the metal grounding layer 3 are rectangular and the lengths of the long sides and wide sides of the three are respectively equal. The upper dielectric board 1, the metal grounding layer 3 and the lower dielectric board 2 are stacked together from top to bottom, and the metal grounding Layer 3 is attached to the upper surface of the lower dielectric board 2, the microstrip radiation group is arranged on the upper dielectric board 1, the microstrip feeder 4 is attached to the lower surface of the lower dielectric board 2, and the long side extension direction of the upper dielectric board 1 is taken as The left and right directions, the broadside extension direction as the front and rear d...

Embodiment 2

[0021] Embodiment two: this embodiment is basically the same as embodiment one, the difference is as follows:

[0022]In this embodiment, the length of the long side of the first rectangular metal block 10 is 13.89 mm, and the length of the wide side is 11.44 mm. The first group of metallized through holes 11 is formed by 16 metallized through holes arranged at intervals from left to right. The second group of metallized through holes 12 is formed by 16 metallized through holes arranged at intervals from left to right, and the third group of metallized through holes 13 is formed by 15 metallized through holes arranged at intervals from front to back. The center distance between every two adjacent metallized through holes in the metallized through holes 11 and the center distance between every two adjacent metallized through holes in the second group of metallized through holes 12 are both 0.82 mm. The center distance between every two adjacent metallized through holes in the t...

Abstract

The invention discloses a series-fed planar printed array antenna, which includes an upper dielectric board, a lower dielectric board, a microstrip radiation group, a metal ground layer and a microstrip feeder line, and the microstrip radiation group includes a first microstrip radiation unit, a second The microstrip radiating unit, the third microstrip radiating unit, the fourth microstrip radiating unit and the fifth microstrip radiating unit, the first microstrip radiating unit, the second microstrip radiating unit, the third microstrip radiating unit, the fourth microstrip radiating unit The working modes of the strip radiating unit and the fifth microstrip radiating unit are both magnetic dipole working modes, and are arranged at intervals from left to right according to the Taylor line array rule. The second microstrip radiating unit, the third microstrip radiating unit, the fourth microstrip radiating unit and the fifth microstrip radiating unit are connected; the advantage is that on the basis of simple structure and low profile, it has low side lobe and can transmit and receive vertically Polarized electromagnetic waves.

Description

technical field [0001] The invention relates to a planar printed array antenna, in particular to a series-fed planar printed array antenna. Background technique [0002] The planar printed array antenna has the advantages of small size, light weight, low profile and simple processing and fabrication, and has broad application prospects. The existing planar printed array antenna mainly has two feeding methods: series feeding and parallel feeding. According to the feeding method, planar printed array antennas are divided into two categories: series-fed planar printed array antennas and parallel-fed planar printed array antennas. Compared with the parallel feeding method, the series feeding method has a shorter feeder line, which can effectively reduce the radiation and line loss caused by the feeder line, and improve the antenna efficiency. Therefore, the series-fed planar printed array antenna is relatively , in which the radiating units are arranged compactly, which can re...
