Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] The present invention designs two folded planar microstrip reflective array antennas whose scanning angles are 0 degree and 45 degree respectively.
[0025] Such as figure 1 As shown, the feed source adopts a 2×2 microstrip patch array, and the array element is a microstrip patch with a length of 12.9mm and a width of 8.7mm. A one-to-four power splitter can be used, but the performance is not as good as two-stage one-two The power divider is good, but the design is relatively troublesome, but the one-point two-power divider is easy to realize, convenient to process, and the performance is good, which meets the requirements, so this feed uses a two-stage one-point two power divider for feeding.
[0026] figure 1 The dimensions in the following table:
