Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a small, broadband interface structure integrated antenna. Background Technology

[0002] Currently, broadband antennas are mostly used in exam room monitoring and interference equipment, capable of monitoring and interfering with cheating signals within a wide frequency range of 30MHz-8GHz. However, existing exam room monitoring and interference equipment antennas generally suffer from the following drawbacks: 1. A significant conflict between physical size and installation convenience: Traditional broadband antennas often employ complex structures such as butterfly, logarithmic periodic, and gradient slots to achieve impedance matching and pattern control, resulting in large unit size, heavy weight, and cumbersome installation. 2. A lack of environmental integration design concepts: Existing products mostly use fiberglass shells, with surface treatment processes limited to basic protection. In the deployed environment, the broadband antenna creates a noticeable visual difference with the background, affecting the equipment layout and aesthetics. Furthermore, the conformal design of the antenna radiating element to the carrier surface is lacking. 3. Insufficient balance between functional implementation and structural optimization: To meet the broadband VSWR requirements, existing designs must retain redundant matching networks and circuits. These shortcomings not only restrict the efficiency of equipment deployment but also weaken the effectiveness of interference monitoring to some extent. Summary of the Invention

Employing a miniaturized design, it innovatively integrates the RF interface and antenna housing into a single structure, significantly reducing space requirements, installation difficulty, and time costs.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] This utility model embodiment provides a small, broadband interface integrated antenna to solve the problems of large size and cumbersome installation that are common in existing antenna products for examination room monitoring interference equipment; such as Figure 1 As shown, Figure 1 This is a schematic diagram of the integrated antenna structure of the small broadband interface structure according to an embodiment of the present invention. The antenna of the present invention includes:

[0015] The antenna assembly includes a rainproof cap 101, an upper antenna element 102, a lower antenna element 109, a connecting sleeve 104, and a stainless steel lower cover 111. The rainproof cap 101, made of polypropylene, is installed above the upper antenna element 102 and effectively resists rainwater intrusion, ensuring the safety of internal components. The connecting sleeve 104 houses an upper antenna cone 103 and a lower antenna cone 106. The upper antenna element 102 and the upper antenna cone 103 are fixedly connected by Phillips head screws 105, and the lower antenna element 109 and the lower antenna cone 106 are also fixedly connected by Phillips head screws 105. The upper antenna element 102 and the lower antenna element 109 are connected by the connecting sleeve 104 to form a hollow cylindrical steel tube structure, providing a foundation for antenna signal transmission. The stainless steel lower cover 111 connects to the interior of the lower antenna element 109. The connection between the stainless steel lower cover and the antenna lower vibrator is sealed with AB glue to further enhance the product's sealing and protection. An SMA RF connector 108 is fixedly mounted on the antenna lower cone 106 using Phillips head screws 107. The center conductor of the SMA RF connector 108 is electrically connected to the antenna upper cone 106. This electrical connection refers to the connection between the SMA RF connector 108 and the antenna upper cone 106 achieved by melting solder wire, ensuring stable signal transmission. An N-JB2 RF connector 112 is located inside the stainless steel lower cover 111. The N-JB2 RF connector 112 is used to receive or transmit electromagnetic signals. The N-JB2 RF connector 112 is connected to the SMA RF connector 108 via an RF coaxial cable 110 to achieve signal transmission.

[0016] See Figure 1 , Figure 1The upper antenna element 102 and the upper antenna cone 103 constitute the left half-conductive arm of the receiving / transmitting unit, while the lower antenna cone 106 and the lower antenna element 109 constitute the right half-conductive arm. When the axis of the conductive arm is parallel to the electric field direction of the incident electromagnetic wave, the electric field forces the free electrons within the conductive arm to undergo periodic directional migration, forming an alternating induced current with the same frequency as the incident wave in the closed loop. This current is transmitted to the examination room monitoring interference device via the N-JB2 RF connector 112 interface. In reverse operation, the examination room monitoring interference device injects an interference suppression signal into the center feed point of the conductive arm through the N-JB2 RF connector 112 interface. Utilizing the impedance matching characteristics of the antenna, it excites equal-amplitude, opposite-phase alternating currents on both arms, thereby achieving efficient transmission of electromagnetic signals. By employing multi-physics-based collaborative optimization design of the structural parameters of the antenna upper vibrator 102, antenna upper cone 103, antenna lower cone 106, and antenna lower vibrator 109, and utilizing innovative technologies such as gradient layer impedance matching and cone angle reverse compression, 8GHz broadband signal processing capabilities can be successfully achieved. Furthermore, the ingenious integrated output interface design deeply integrates the RF connector with the antenna radiator, significantly enhancing the device's portability and installation efficiency while ensuring electrical performance, effectively meeting the rapid deployment needs of scenarios such as emergency monitoring in examination rooms.
