Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 Shown, a kind of X / Ku frequency band dual-frequency dual-polarized microstrip flat plate reflectarray antenna includes: a feed source and a microstrip flat plate reflectarray; the feed source is a pyramidal horn antenna; the microstrip flat plate reflectarray includes Several double parallel vibrator units, the double parallel vibrator unit includes two parallel vibrator patches with different lengths and the same width: a long vibrator patch and a short vibrator patch; these units are arranged on the dielectric base a.
[0023] Such as figure 2 As shown, the length of the long vibrator patch is a, the length of the short vibrator patch is b, b=k*a, k is a constant; the widths of the long vibrator patch and the short vibrator patch are w, the distance between the long vibrator patch and the short vibrator patch is d....
