Radio frequency (RF) antennas are classified into several categories based on their radiation characteristics, structure, and application scenarios. The core types and their suitable applications are as follows:

I. Classification by Radiation Direction

1. Omnidirectional Antennas: Radiate uniformly in 360°, with a gain of 2-5 dBi. Examples include rod antennas and whip antennas. Suitable for mobile phones, routers, and LoRa nodes, providing short-range multi-device communication coverage.

2. Directional Antennas: Concentrate the signal in one direction, with a gain of 8-24 dBi. Examples include Yagi antennas and parabolic antennas. Used for long-distance point-to-point communication (e.g., base station relay, satellite reception).

II. Classification by Structural Form

1. Built-in Type:

Ebyte PCB Antenna: Integrated circuit board, low cost and miniaturization, suitable for wearable devices and IoT sensors;

Ebyte FPC Antenna: Flexible material, suitable for curved devices (e.g., smartwatches), offering flexible installation.

2. External Types:

Ebyte Adhesive Rod Antenna: SMA interface, omnidirectional coverage, commonly found in wireless modules and indoor gateways;

Ebyte Magnetic Antenna: Attachment-type installation, medium gain, suitable for temporary monitoring equipment and vehicle-mounted scenarios;

Ebyte Fiberglass Antenna: High gain and weather-resistant (-45~110℃), suitable for outdoor base stations and industrial long-distance communication;

Ebyte Array Antenna: Multi-element combination, beam controllable, used in 5G base stations and radar systems.

III. Classification by Frequency Band Adaptability

Ebyte Low Frequency Band (<1GHz): Whip and loop antennas, suitable for broadcasting and IoT LoRa (433MHz);

Ebyte Mid-to-High Frequency Band (1-6GHz): Patch and log-periodic antennas, suitable for mobile phones and WiFi (2.4/5GHz);

Ebyte High Frequency Band (>6GHz): Parabolic and phased array antennas, suitable for satellite communication and millimeter-wave radar.

Key selection criteria: Match the device based on communication distance (omnidirectional for short distances, directional for long distances), device size (built-in PCB/FPC for small devices), and environment (weather-resistant fiberglass for outdoor use).
