Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] refer to figure 1 . The embedded invisible circularly polarized antenna of the present invention is composed of a printed board 1 , a cable assembly 10 , a stripline feed network 11 and a high frequency connector 9 .

[0025] The printed board 1 includes copper foil on the printed board, a feed sheet 2 , a feed cable 3 and a balanced current cable 4 . The cable assembly 10 includes a feeder cable and a 3 balancing current cable 4 . The printed board 1 is fixed above the upper bottom plate 7 by the support column 5 . The copper clad substrate as the radiation surface of the antenna is placed on the top of the entire antenna. The size of the antenna may be: length*width*height=0.38λ*0.38λ*0.09λ.

[0026] The cable assembly 10 is composed of two feeder cables 3 and two balanced current cables 4 in a 2×2 rectangular array on the copper foil substrate of the printed ...

Abstract

The invention provides an embedded invisible circular polarized antenna, aiming at providing the embedded invisible circular polarized antenna with wide wave beam coverage range and coverage area, which can bear high power, receive signals in a plurality of frequency segments, receive and transmit circular polarized electromagnetic wave within wide-angle range and realize wide-angle coverage. Theembedded invisible circular polarized antenna comprises a printed circuit board (1), a cable component (10), a strip line feed network (11), a high-frequency connector (9); the cable component is composed of two feed cables (3) and two balanced current cables (4) arranged on a printed board by a 2*2 rectangular array, wherein the two feed cables are connected with the port (20) and port (21) of a3dB directional coupler (6) in the strip line feed network, an outer conductor of the two balanced current cables is connected with the copper foil on the printed board, and the high-frequency signalcurrent of an outside signal source is fed into the 3dB directional coupler by the high-frequency connector and then is distributed to the cable component, then is fed into the printed board by crossfeed sheets (2) on the feed cables (3).

Description

technical field [0001] The present invention relates to a circularly polarized antenna capable of simultaneously receiving signals in multiple frequency bands, more specifically, the present invention relates to an embedded invisible circular antenna capable of receiving and transmitting circularly polarized electromagnetic waves within a wide-angle range and enabling wide-angle coverage polarized antenna. Background technique [0002] With the continuous advancement of wireless communication technology, wireless communication equipment has begun to develop in the direction of miniaturization and broadband, and broadband wireless products with characteristics such as light, thin, short, and small will become the mainstream in the future. Although the traditional dipole antenna has good transmission characteristics, its size specifications cannot meet the development trend of miniaturization. Microstrip antennas that are small in size, light in weight, low in cost, easy to m...
