Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] see figure 1 , the patch antenna of the present invention is printed on a size of 35×17×1.6mm 3 On the FR4 dielectric substrate, the upper and lower surfaces of the dielectric substrate are covered with a radiation patch on the upper surface and a conductive layer on the lower surface, and the material is silver. The radiation patch and the conductive layer are connected through SMA connectors; the radiation unit on the upper surface is a wine glass-shaped patch, and the radiation patch includes the front end 1 of the patch whose aperture decreases from a large gradient and a stepped rectangular microstrip connected to the tail of the front end 1 of the patch. The input impedance of the feeder 2 and the microstrip feeder 2 is 50 ohms, and the front end of the patch 1 is a gradient structure left by cutting the triangular part and the trapezoidal part ...

Abstract

An ultra-wideband tri-trap antenna comprises a dielectric substrate. The upper surface and the lower surface of the dielectric substrate are respectively coated with a radiation patch and a conductive layer. The radiation patch comprises a patch front end in the diameter decreasing and a micro-strip feeder line connected to the tail of the patch front end. The conductive layer comprises a base plate with arc-shape edge and a split ring reflector arranged above the base plate with arc-shape edge. The arc-shaped edge of the base plate with arc-shape edge protrudes upwards. The base plate with arc-shape edge is provided with a U-shaped groove with a downward opening. The split ring reflector comprises an upper ring with a rectangular opening, a lower ring with a rectangular opening and symmetrical branches arranged outside the rings. According to the ultra-wideband tri-trap antenna, straight grooves in both inner side edges of the U-shaped groove and wave grooves outside the U-shaped groove are used for trapping the frequency band of a wireless local area network and the C-band respectively, and the non-base plate area at the bottom of the antenna is used for trapping the downlink band of the X-band through the split ring reflector with double openings and the branches. The ultra-wideband tri-trap antenna has the advantages of being novel in overall structure, small in size, high in trap quantity, good in trap form and the like.

Description

technical field [0001] The invention relates to an ultra-wideband antenna, in particular to an ultra-wideband triple-notch antenna. Background technique [0002] The microstrip antenna has the advantages of small size, simple structure, and easy integration, so the microstrip antenna has a wide range of applications. In recent years, research on ultra-wideband (Ultra-Wideband) antennas has attracted more and more attention, especially after the FCC specified the 3.1-10.6GHz frequency band as a civilian frequency band in 2002, and developed ultra-wideband antennas for this frequency band. Subsequently, there is overlap with some existing frequency bands, such as wireless metropolitan area network (WiMax, 3.3-3.6GHz), C-band satellite communication (3.7-4.2GHz), wireless local area network (WLAN, 5.2-5.8GHz), X Band satellite communication (7.25-7.75GHz, 7.9-8.4GHz), etc., so the practicability of the ultra-wideband notch antenna is very strong.
