Embodiment 1

[0022] See figure 1 , figure 1 This is a schematic structural diagram of a broadband microwave flat panel slot antenna provided by an embodiment of the present invention. The broadband microwave flat slot antenna includes a substrate 10 , a radiating pole 20 and a feeding network 30 , wherein the radiating pole 20 is arranged on one surface of the substrate 10 , and the feeding network 30 is arranged on the other surface of the substrate 10 . When the antenna sends a signal, the feeding network layer 30 transmits the electromagnetic wave signal therein to the radiating pole 20, and the radiating pole 20 emits the signal.

[0023] See figure 2 , figure 2 It is a schematic structural diagram of a radiation pole provided by an embodiment of the present invention. The substrate 10 is made of an insulating material, such as a resin material. The resin material for the substrate has the advantages of being cheap and easy to process. The surface of the substrate 10 is partially...

Abstract

The invention relates to a broadband microwave panel slot antenna which comprises a substrate (10), a radiation pole (20) and a feed network (30), the radiation pole (20) is arranged on one surface of the substrate (10), and the feed network (30) is arranged on the other surface of the substrate (10); the radiation pole (20) comprises a rectangular feeder line (21), a fan-shaped branch knot (22) and a semi-elliptical gap (23), the rectangular feeder line (21) is communicated with the fan-shaped branch knot (22), and the semi-elliptical gap (23) is arranged on the periphery of the rectangular feeder line (21) and the fan-shaped branch knot (22) to form a closed cavity; the feed network (30) forms a closed ring, and the feed network (30) covers the radiation pole (20) along the width direction of the substrate (10). According to the slot antenna provided by the invention, the rectangular feeder line, the semi-elliptical slot and the fan-shaped branch knot are arranged in a combined manner, and the interval of the slots is gradually changed, so that the impedance change of the antenna is very small, the antenna resonance effect in a broadband range is realized, and the slot antenna has a relatively good bandwidth characteristic and can meet the high-speed and high-resolution requirements of communication equipment and detection equipment.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a broadband microwave slab slot antenna. Background technique [0002] At present, with the rapid development of global communication services, wireless mobile communication technology, which is the main means of personal communication in the future, has attracted great attention. Excellent performance plays an important role in the success or failure of wireless communication engineering. [0003] With the application of antennas in different scenarios, the demand for high-speed communication and high-resolution detection continues to increase. In order to meet the high speed and high resolution requirements of communication equipment and detection equipment, the antenna needs to have broadband operation performance. Due to its low profile, easy integration, low loss and large impedance bandwidth, slot antennas have become the preferred choice for communicati...
