Technical Field

The utility model belongs to the technical field of the antenna, especially, relate to a novel walk line antenna and electronic equipment.

Background

An antenna is now a converter 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 use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. At present, some electronic devices, such as mobile phones, have very high intelligent degree, the environment of the antenna of the mobile phone is too complex, the clearance of the antenna is not enough, but the standards of more and more antennas in frequency bands are not reduced, the design difficulty of the antenna is more and more, the bandwidth is insufficient, the head-hand test of a person is affected, signals of a user are very poor when the user makes a call or surfs the internet, the available space of the antenna is few, but the bandwidth of the antenna needs enough clearance of the antenna and enough area to meet the performance requirement, the traditional solution is to add an antenna switch for debugging, but the loss of the antenna is too large when the antenna is switched from 900M to 700M through the switch, and the original bandwidth still cannot.

In summary, there is a need to solve the above technical problem by providing two parasitic antennas to feed a main antenna.
