Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figure 1a , Figure 1b As shown, a double-notch ultra-wideband antenna includes a dielectric substrate 1, a ground plane 3, a microstrip radiation patch 2 and a microstrip feeder 4, and the microstrip radiation patch 2 and the microstrip feeder 4 are fixed on the dielectric substrate 1 On the front, the microstrip feeder 4 leads from the edge of the dielectric substrate 1 to the microstrip radiation patch 2 and connects them. Two stepped grooves 21 are symmetrically arranged on the central axis of the sheet 2, and each stepped groove 21 is composed of a first horizontal groove, a second horizontal groove and a vertical groove, and the first horizontal groove is close to the small end of the microstrip radiation patch 2 , the second horizontal groove is away from the small end of the microstrip radiation patch 2, the first horiz...

Abstract

The invention discloses a double-trapped-wave ultra-wide-band antenna. The double-trapped-wave ultra-wide-band antenna is mainly characterized in that two stepped grooves are formed at the large-head end of a micro-strip radiation patch with respect to the central axis of the micro-strip radiation patch in a bilaterally-symmetrical mode, each stepped groove consists of a first horizontal groove, a second horizontal groove and a vertical groove, the first horizontal groove and the second horizontal groove are equal in length, the sum of the lengths of the first horizontal groove and the second horizontal groove is smaller than the length of the vertical groove, the left-side edge of the first horizontal groove of the first stepped groove formed in the left side coincides with the left-sided edge of the micro-strip radiation patch, the right-side edge of the first stepped groove formed in the right side coincides with the right-sided edge of the micro-strip radiation patch, a semi-closed annular groove is formed in the small-head end of the micro-strip radiation patch, and the length of each stepped groove and the length of the semi-closed annular groove are one half or quarter of the wave length of suppressed mid-band frequency. The double-trapped-wave ultra-wide-band antenna can achieve ultra-wide-band communication and mutual compatible and cooperative communication of mutual interference communication systems.

Description

technical field [0001] The invention relates to a planar printed antenna, in particular to a double-notch ultra-wideband antenna. Background technique [0002] Ultra-wideband technology is a new type of wireless communication technology that solves the major problems related to propagation that have plagued traditional wireless technology for many years. It has the characteristics of insensitivity to channel fading, low power spectral density of transmitted signals, low interception capability, and low system complexity. , Can provide centimeter positioning accuracy and other advantages. Since the U.S. Federal Communications Commission (FCC) classified the 3.1-10.6GHz ultra-wideband frequency band as a commercial frequency band in 2002, the ultra-wideband planar antenna is due to its small size, wide bandwidth, certain radiation efficiency, omnidirectional radiation characteristics, and simple manufacturing process. , low cost, easy integration and high transmission rate ha...
