It takes (at least) two (ports) to MIMO.....

In wireless applications, where download speed is king, network devices are turning to MIMO antenna systems to help provide the bandwidth speeds customers require. The use of MIMO (Multiple In, Multiple Out) antennas in WiFi and LTE applications is helping to improve communcation performance and often critically in mobile applications download speeds.

These MIMO antennas can use spatial and/or polarisation (pattern) diverstity to improve signal at both the receive and transmit ends of the network.

From our wide portfolio antennas, we have summarised some our more popular MIMO antennas here for WiFi and 4G applications:

08-ANT-0943-3X - Triple Feed Dual Band (2-3GHz/4.9-5.9GHz) Indoor MIMO Antenna

The 3 port MIMO-Dual Band antenna manufactured by MP Antenna is a low profile Multi-Polarized MIMO (Multiple-Input-Multiple-Output) antenna  offering continuous wideband performance ( from 2-3GHz/4.9-5.9GHz for fixed installations for both indoor and outdoor applicaitons. The 3X-MIMO-Dual With three separate antenna feeds, it facilitates maximum diversity for 2.4 GHz and 5 GHz WiFi and WiMAX frequencies. This Triple Feed antenna has a built in ground plane and is supplied with low loss cables for maximum efficiency.

MPMI MIMO WLAN - Multiple Port MIMO WLAN antenna


The MPMI MIMO WLAN  from PCTEL omni antenna products are omnidirectional, operating at both the 2.4 GHz and the 5 GHz band. They are designed to support access points offering 802.11n coverage. The antennas are suitable for both indoor and outdoor installations, and include mounting hardware for wall/mast or ceiling mount applications, depending on model.

Models include:

MPMI2458-3-RPSMA .

FP2458-DP3X3 - Directional MIMO Panel antenna

The FP2458-DP3X3 is a dual-band MIMO WiFiantenna that offer spatial and polarization diversity across the 2.4-2.5 GHz and 5.1-5.9 GHz broadband wireless frequencies in a discrete, low-profile housing. This antenna was conceived to address enhanced coverage for areas with large numbers of mobile
data users such as stadiums, concerts etc. It has been designed with both outdoor and in-building installations in mind that are utilizing 802.11n wireless LAN access points across the 2.4 and 5 GHz frequency bands.

For 4G and LTE frequencies, we have a range of MIMO products:

LPM8270 - MIMO 4G Multiband Outdoor panel antenna

LPM8270 4G/Multiband Outdoor Directional MIMO Antenna

The LPM8270 from EAD is a 4G/3G/GSM multiband outdoor directional high gain antenna offering 8/9 dBi gain across the frequency range. It is dual polarised with 2 ports (2 x N-Female) to connect to 4G routers and modems requiring diversity across 2 antenna ports. Jumper cables can be customised to suit.

WA700/2700 - MIMO 4G Multiband Mobile antenna

WA700/2700 MIMO Window Mount antenna

The WA700_2700 is a 4G, 3G, GSM and cellular dual port MIMO antenna for mobile applications - supplied with suction cups for window mount, this antenna comes into its own in non-fixed environments where two ports MIMO antennas is required to improve download speeds.
