Dipole Antennas: Dual Band 2.4GHz & 5GHz
Dipole Antennas: Dual band in 2.4GHz-5GHz bands
Dipole dual-band antennas for Wi-Fi are omnidirectional antennas that radiate RF (radio frequency) signals in both the 2.4GHz and 5GHz frequencies. The dual-band WiFi dipole antenna radiates and receives signals in a 360-degree angle around it. The antenna is designed to be mounted directly onto the RP-SMA female or SMA female connector of a client or radio device. The right angle versions are designed to be adjusted by up to 90 degrees or less.
Since they are vertically polarized, dual-band antennas for Wi-Fi find usage in many communication and machine to machine applications that include mesh networking, remote monitoring, and telemetry applications. Most SMA and RP-SMA connectors are gold plated for low loss and hence they provide superior performance for longer.
Similar to most dipole antennas dual-band antennas for Wi-Fi have Reverse Polarity SMA for RP-SMA. As such, the gender determination is counterintuitive with the gender referring not to the threads but rather to the pins. The SMA male and the RP-SMA have threads on the inside while the SMA male is designed with a pin in the threaded chamber and RP-SMA male comes with a socket in the chamber.
The high gain of the dual-band antennas and the omnidirectional coverage for Wi-Fi makes them suitable for a variety of applications such as large indoor spaces, warehouses, building, and marine installations. Other uses of the dual-band antennas include:
- 802.11ac Wi-Fi Routers and Access points
- 802.11b/g/n applications
- WLAN and WiFi systems
- Bluetooth, LoRa, ZigBee
- 4.9 GHz Public safety bands
- Wireless Video systems
- Mobile and multipoint applications
- Public wireless hotspots
