Antenna Devices

Antenna performance can greatly affect the range and reliability of your product, however these devices are often an afterthought in the process of an RF design. Digi-Key has a large offering of antennas at almost any frequency with multiple style options to best fit your application such as whip antennas, high gain antennas, and chip antennas. Whip styles are also available in various connectorized versions or with cable attached.

860 ~ 960MHz

Linx 916MHz ½ Wave RPSMA Whip AntennaThe 860 ~ 960MHz band is popular in many countries due to the fact you can send almost any analog or data signal, specifically the 902 ~ 928MHz band in the US and the 868MHz band in the EU. The 902 ~ 928MHz band is an ISM band in the US, but check local regulations to see which frequencies are unlicensed to use in your area. In the US, this Frequency band is regulated by CFR Title 47 Part 15.247.

2.4 ~ 2.5GHz

Antenova 2.4GHz Titanis AntennaThe 2.4GHz band is a popular ISM (Industrial, Scientific and Medical) band worldwide. Multiple channels are available depending on your region. Some popular applications used in this band include Bluetooth, WiFi/WLAN, and IEEE 802.15.4-based solutions. This band is limited for operation in the US under FCC CFR Title 47 Part 15.247 and 15.249 (Radiated Power Limits)

4.9 ~ 5.875GHz

Nearson Rubber Duck AntennaThe 4.9 ~ 5.875GHz band is an ISM (Industrial, Scientific, Medical) band for use in the US and many other countries. This band is regulated in the US by FCC Title 47 Part 15.247 and 15.249 (Radiated Power Limits). A popular application used in this band is IEEE 802.11a, and dual-band operation of the draft specifications of the 802.11n.   730-1013-ND (pictured)
