The Low-Down on Log Periodic Antennas

June 23, 2016 at 8:00 AM


Deciding which frequency to use for your wireless application can be a downright tedious. But what if you didn’t have to choose?  What if there was an antenna that combined several frequencies into one? Log periodic antennas have that capability. Here, we’ll give you the low-down on them.


In the world of Wi-Fi antennas, log periodic antennas stand-out as superior multi-taskers. They are directional, wide-band, narrow-beam antennas that utilize multiple elements. They can be used for a variety of wireless applications where a wide range of frequency coverage is desired.


Performance-wise, the broadband characteristics of log periodic antennas allow for very good gain and directivity while operating on multiple frequencies. And because they combine several frequencies into one antenna, they eliminate the need for purchasing different antennas for each frequency, which also simplifies installation.  


Log periodic antennas are ideal for Distributed Antenna Systems (DAS) networks, where support for cellular, PCS and Wi-Fi communication frequencies is required. These antennas can also be used in any application that uses broadband frequencies in a wireless network.


Some applications include:

•  802.11a/b/g/n and 802.11ac Wi-Fi Networks

•  Distributed Antenna Systems (DAS)

•  Ultra Wide Band, UWB applications

•  Homeland Security and Public Safety Services: Fire, Police, Security


If you need a versatile antenna that combines multiple frequencies, a log periodic antenna may be your best bet. L-com offers several log periodic antennas and can even manufacture custom antennas to your specifications.
