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.
