Description

Folding indoor antenna Technical Field The present utility model relates to an antenna, and more particularly, to a folded indoor antenna. Background An antenna is a transducer that converts 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 for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all rely on antennas to work when information is transmitted by electromagnetic waves. In the prior art, patent application number CN202320182016.3 discloses a folding indoor antenna who just conveniently accomodates, including the sucking disc, the upper portion of sucking disc is provided with the body, the inside of body is provided with first flexible pipe, the inside of first flexible pipe is provided with the second flexible pipe, the lateral surface of body, first flexible pipe and second flexible pipe is provided with the holding ring, the mounting groove has all been seted up to the inside of holding ring, the inside swing joint of mounting groove has the antenna boom, can accomodate the antenna boom in the holding ring to with first flexible pipe and the shrink of second flexible pipe in the body. However, in the above-mentioned technique, since the antenna rod is exposed outside the tube body, and is easy to collide with and damage when being stored and carried, and is easy to hook on other objects, in order to fully retract the antenna rod, the antenna rods on the first telescopic tube and the second telescopic tube need to be arranged in a abdicating way, so that the antenna rods on the first telescopic tube and the second telescopic tube are not positioned on the same plane, and therefore, when the antenna rods on the first telescopic tube and the second telescopic tube are fully opened, the space occupation is relatively large.
