Log-periodic antennas are wideband, directional antennas with core advantages including wide operating bandwidth, stable frequency response, and good directional consistency, while also offering high gain. Therefore, they are widely used in scenarios requiring cross-frequency band signal transmission and reception. The following are the main application areas and specific scenarios:

1. Shortwave/UHF Communication

Application Scenarios: Military shortwave communication, emergency communication, field intercom, etc. The shortwave frequency band has a wide range (3–30 MHz), which ordinary narrowband antennas cannot cover. Log-periodic antennas can maintain stable performance across a wide frequency band, enabling long-distance, cross-frequency band voice and data transmission, suitable for scenarios without fixed communication networks, such as in the field and disaster relief.

Features: Supports simultaneous operation of multiple channels, suitable for mobile emergency communication vehicles and field communication base stations.

2. Broadcast Television Signal Reception

Application Scenarios: Outdoor reception of terrestrial digital television (DTMB) and FM radio, especially in scenarios requiring simultaneous reception of multiple frequency band television signals, such as remote areas and homes/groups requiring multi-channel coverage.

Features: Compared to ordinary Yagi antennas, it has a wider bandwidth, is compatible with different frequency band television signals, can receive multiple programs without changing the antenna, and has stronger signal reception stability.

3. Mobile Communication Assisted Coverage

Application Scenarios: Coverage gaps for mobile communication base stations; small cell antennas; used in scenarios with multiple 4G/5G frequency bands, such as urban edges and suburbs, to enhance broadband signal transmission and reception.

Features: Can cover multiple mobile communication frequency bands, reducing the number of antennas deployed and lowering base station construction costs.

1. Radar Systems

Application Scenarios: Broadband early warning radar and reconnaissance radar require the detection of radar echo signals from different targets across a wide frequency band. Log-periodic antennas can adapt to multi-band radar operating modes, enhancing the radar's multi-target detection capabilities.

2. Internet of Things (IoT) and Short-Range Communication

Application Scenarios: Multi-band IoT gateway antennas adapt to cross-band IoT terminal access, meeting the signal transmission and reception needs of IoT devices with different protocols and frequency bands.
