High gain wideband single-pole omni-antenna

The utility model discloses a high gain brand frequency band monopole omnidirectional antenna, which characterized in that the back of bottom plate 2 is arranged with one radio frequency connector, an energizing probe 5 is arranged with the front face of the bottom plate 2, one end of the energizing probe 5 is connected to the radio frequency connector 1 through the hole of the bottom plate 2, the other end of the energizing probe 5 is connected to the original patch 4, the top of the original patch 4 is arranged with parasitical patch 3, the front face of the bottom plate 2 is arranged with a resonant vibration slice 6, the parasitical patch 3 is supported by the resonant vibration slice 6. The utility model can completely realize high plug and wide band. The band width can reach 38 per cent and the plus can reach 4.5dbi, which are obvious better than that of other similar antennas. The utility model features simple structure and lost cost. Moreover, the utility model conforms to electric performance index of communication market. Therefore, this antenna has strong competitiveness.
