An anti-jamming antenna kit is an integrated signal receiving and processing device that aims to reduce external electromagnetic interference and improve communication stability through optimized design and technical means. The following is a detailed analysis based on the latest technical trends and application scenarios:

I. Core technologies and functional features

1. Hardware design innovation

Dual-core integration: For example, the HX-KCZT019 of Harxon Antenna adopts the "four-channel anti-jamming RF chip + baseband processing chip" design, which is 70% smaller than the traditional solution and supports the anti-wideband and pulse interference functions of the BDS-B1 and GPS-L1 frequency bands.

Ceramic multilayer technology: Murata's Radisol device achieves ultra-miniaturization of 0603 size (0.6×0.3×0.2mm) through ceramic technology, which can be directly integrated around the antenna of a smartphone, and suppresses mutual interference between adjacent antennas with low insertion loss (<0.5dB). The effectiveness has been verified in Motorola Wi-Fi antennas.

High temperature resistant materials: Some military kits use high temperature ceramic substrates, which can work for a short time in a 600℃ environment, and reduce carrier resistance through conformal design.

2. Anti-jamming technology solutions

Beamforming and adaptive filtering: The positioning directional antenna dynamically adjusts the beam direction through a digital signal processing algorithm, and can still maintain communication stability in complex electromagnetic environments (such as near 500kV high-voltage lines)318.

Notch filtering and magnetic coupling: Radisol forms a high-Q notch filter through mutual inductance effect, which suppresses the interference frequency band while avoiding loss to the main communication frequency band, and reduces the installation area by 62% compared with traditional LC circuits.

Wideband coverage: The microwave crack antenna project aims to cover the 10-40GHz frequency band, with a gain of ≥30dB and an anti-jamming capability of more than 90dB, suitable for 5G base stations and satellite communications.
