Embodiment Construction

[0030] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, eight aluminum foil strips 6 along the longitude direction and two along the latitude direction are used in this embodiment. The upper and lower parts of the main radiator 3 are conformally attached to the spherical surfaces of two identical small balloons 2 respectively. The main radiator 3 is formed by combining several equal-width aluminum foil strips 6 . The main radiator 3 is symmetrical to the feeder structure connected in the middle. The use of the spherical conformal radiation structure can not only realize the wide-band working characteristics, but also make the manufacture simple and significantly reduce the weight of the antenna. The feed body 4 is located at the geometric center of the antenna, and includes two surface metalli...

Abstract

The present invention discloses an ultra wide band conformal balloon antenna. The antenna comprises a big balloon, a small balloon, a main radiator, a feed body, a gasket and a radio frequency choker. The big balloon is internally provided with the small balloon; the main radiator is conformal to the surface of the small balloon, the main radiator comprises two aluminum foil belts along a latitudinal direction and a plurality of aluminum foil belts along a longitude direction, the widths of the aluminum foil belts are the same, and the main radiator is symmetrical to the feed body; the feed body is connected between the upper portion and the lower portion of the main radiator; the gasket is arranged between the upper portion and the lower portion of the feed body; and the radio frequency choker is arranged at the lower portion of the aluminum foil belts along the latitudinal direction. The ultra wide band conformal balloon antenna is wide in network coverage range, wide in available frequency band, high in data transmission efficiency, convenient and flexible in establishment of a wireless station and low in maintenance cost, and is suitable for a remote measurement system.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an ultra-wideband conformal balloon antenna. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristi...
