Description

technical field [0001] The invention belongs to the technical field of circulators, and in particular relates to a printed circuit board type circulator and a realization method thereof. Background technique [0002] Compared with 4G, the improvement of 5G is all-round. According to the definition of 3GPP, 5G has the characteristics of high performance, low latency and high capacity, and these advantages are mainly reflected in technologies such as millimeter wave, small base station, Massive MIMO, and full duplex. 5G has qualitatively improved compared with 4G in terms of technical indicators such as network capacity, peak rate, and delay. As one of the core technologies of 5G, Massive MIMO breaks the limitation that traditional antennas can only provide horizontal dimensions. By introducing a two-dimensional antenna array, it can realize MIMO in both horizontal and vertical directions at the same time, further improving the space dimension available for MIMO. Multi-antenn...
