Embodiment Construction

[0036] The basic idea of ​​the present invention is: the tapered arm and the coplanar waveguide feeder transmit the current of the RF excitation port to the main radiation ring monopole, and the main radiation ring monopole forms a coupling with the main coupling patch; at the same time, the main radiation ring The monopole transmits the current to the secondary radiating annular monopole through the metal via, and the secondary radiating monopole forms a coupling with the secondary coupling patch.

[0037] The present invention will be described in detail below through specific embodiments and accompanying drawings.

[0038] An ultra-wideband antenna such as figure 1 and figure 2 As shown, the device includes: a main radiating annular monopole 13, a main coupling patch 14, a tapered arm 12, a coplanar waveguide feeder 11, a secondary radiating annular monopole 15, and a secondary coupling patch 16; figure 2 For top view.

[0039] Among them, the main radiating annular mo...

Abstract

The invention discloses an ultra-wideband antenna, a coplanar waveguide feeder, one end of which is connected to a radio frequency excitation port of a PCB substrate, and one end connected to a gradient arm; one end of the gradient arm is connected to a coplanar waveguide feeder, and the other end is connected to a main radiation ring The monopole is connected; the main radiating ring monopole is connected with the gradient arm; the main coupling patch is located in the middle of the main radiating ring monopole; the secondary radiating ring monopole is connected to the main radiating ring monopole through a metal via The sub-connected; the secondary coupling patch is located in the middle of the secondary radiating ring monopole. The invention also discloses an ultra-wideband terminal. Using the antenna and the terminal described in the invention reduces the space used, facilitates the ultra-thinning of the terminal, widens the frequency band, and enables the terminal to work in the ultra-wideband range.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an ultra-wideband antenna and a terminal. Background technique [0002] With the development of the world economy, mobile communication is constantly evolving from the third generation to the fourth generation, and the demand for multi-mode, multi-band, and multi-system mobile terminals is becoming stronger and stronger, such as world-mode mobile phones, data cards, etc., as mobile The front-end antenna of the terminal, how to achieve omni-directional coverage of 0.8GHz-5.5GHz ultra-broadband with a single antenna in a compact space, so as to save the space and cost of the mobile terminal, which is conducive to the miniaturization and ultra-thin development of the mobile terminal. The design of the antenna has a great test. [0003] At present, the widening antenna frequency band technology is mainly limited to the improvement of planar inverted F antenna (PIFA), inverted F antenna (IFA)...
