Therefore, the number of array elements of the small-size antenna array can be greatly reduced when the array antenna gain is retained unchanged, with the single-wire helical antenna being an array element. In order to improve the gain, single-wire helical antenna usually has more turns, therefore having a greater height, a compression-release device can be used to greatly reduce the height of the antenna in the non-working state, and it is especially suitable for large-size applications at low-frequency.
