Abstract

The invention discloses a Ka-band standing wave type series-fed microstrip line array antenna, a Ka-band standing wave type series-fed microstrip area array antenna and manufacturing methods thereof.The microstrip line array antenna comprises a dielectric substrate, a ground layer, a main feed line, a feed line and a series-fed microstrip line array. The main feed line and the series-fed microstrip line array are both connected to the upper surface of the dielectric substrate. The ground layer is connected to the lower surface of the dielectric substrate. The series-fed microstrip line arraycomprises a first impedance transform matcher and a plurality of array elements. The microstrip area array antenna includes a dielectric substrate, a ground layer, a main feed line, a plurality of second impedance transform matchers, and a plurality of series-fed microstrip line arrays. The main feed line, the plurality of second impedance transform matchers and the plurality of series-fed microstrip line arrays are all connected to the upper surface of the dielectric substrate. The ground layer is connected to the lower surface of the dielectric substrate. One end of the series-fed microstripline array is open-circuited, and the other end of the series-fed microstrip line array is connected to the main feed line through the second impedance transform matchers. The incident wave and the reflected wave are superimposed on the main feed line to realize standing wave transmission. The antenna structure is simplified by using the compact structure and simple design of the series-fed network.

Description

technical field [0001] The invention belongs to the field of antennas, and relates to a Ka-band standing wave series-fed microstrip linear array antenna, an area array antenna and a manufacturing method. Background technique [0002] Compared with other types of antennas, microstrip antennas have a series of advantages such as small size, free structure, low profile, easy integration and low cost, and are widely used. And with the in-depth research and application development of wireless communication, especially in the 5G era that has come, the spectrum resources of low-end frequencies are crowded. Even if the technology of expanding the channel spectrum capacity is adopted, it cannot meet the application needs of wireless communication in the future. In order to obtain a high-speed, high-efficiency, and wide-band wireless communication system, new spectrum resources must be extended to high-end frequencies. Therefore, the millimeter-wave frequency band has become a hot spo...
