Embodiment

[0015] Example: such as figure 1 Shown, this car, marine radio signal receiving antenna have antenna casing 1, and described casing 1 is provided with radio receiving antenna 2, and described radio receiving antenna 2 one end is provided with antenna signal output end 3, and described antenna signal output end 3 The wireless connection element 4 is connected with the antenna amplifier signal input end 5, the bottom of the antenna housing 1 is equipped with a mounting base plate 6, the upper end surface of the antenna housing 1 is arc-shaped, and the radio receiving antenna 2 is located in the antenna housing 1 and distributed along the longitudinal direction of the arc-shaped surface of the antenna housing 1, the radio receiving antenna 2 and the antenna housing 1 have a gap 7.

[0016] In this embodiment, the width of the gap 7 in the vertical direction is at least not less than the diameter of the radio receiving antenna 2, from figure 1 It can be seen that the gap 7 is rou...

Abstract

The invention discloses a radio signal receiving antenna for a vehicle and a ship. The radio signal receiving antenna for the vehicle and the ship comprises an antenna shell, wherein a radio receiving antenna is arranged in the antenna shell; an antenna signal output end is arranged at one end of the radio receiving antenna and is connected with an antenna amplifier signal input end through a wireless connection element; a mounting base plate is mounted at the bottom of the antenna shell; the upper end face of the antenna shell is arc-shaped, the radio receiving antenna is located at the upper part of the inner side of the antenna shell and is distributed in a longitudinal direction of the arc-shaped surface of the antenna shell, and an interval is reserved between the radio receiving antenna and the antenna shell. According to the radio signal receiving antenna for the vehicle and the ship, the upper end face of the antenna shell is set to be the arc-shaped surface, thereby strengthening omnidirectional receiving of antenna signals; furthermore, the existence of the interval, which is reserved between the radio receiving antenna and the antenna shell, is used for improving signal receiving intensity; due to the existence of the interval, after reflected and superposed for multiple times, the signals are reinforced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a radio signal receiving antenna for vehicles and ships used for receiving signals. 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 rece...
