AERIAL CONTROL SYSTEM AND MULTI-FREQUENCY COMMON AERIAL

摘要

Particularly disclosed is a multi-frequency common aerial, comprising a first high frequency range radiating array and a low frequency range radiating array; the low frequency range radiating array comprises a plurality of low frequency radiating units coaxially disposed along two axes respectively; the low frequency radiating units are staggered to each other in the orthogonal direction of the two axes; the first high frequency range radiating array comprises a plurality of high frequency radiating units, at least some of the high frequency radiating units being coaxially arranged along the same axis; one axis of the low frequency range radiating array coincides with the axis of the first high frequency range radiating array, and the low frequency radiating unit therein has a high frequency radiating unit nested therewith; regarding the low frequency radiating units on the two axes, the symmetrical vibrators adjacent to each other have the same feed-in power, and the symmetrical vibrators away from each other also have the same feed-in power, and the former is greater than the latter. With an improved layout, the multi-frequency common aerial achieves a reasonable dimension while having superior electrical performance.
