ANT-2.4-WRT-MON-SMA

Datasheet ANT-2.4-WRT-MON-ccc 2.4 GHz WiFi External Panel-Mount Antenna The ANT-2.4-WRT-MON is a low-profile, panelmount monopole antenna designed for 2.4 GHz WiFi/WLAN and ISM applications including Bluetooth® and ZigBee®. The ANT-2.4-WRT-MON antenna’s compact size allows it to be mounted securely in enclosures requiring added security. The ANT-2.4-WRT-MON antenna’s compact profile and rugged dome reduces the likelihood of accidental damage versus a whip antenna. The antenna connects to the radio via SMA plug (male pin), RP-SMA plug (female socket) MHF1/ U.FL-type plug (female socket) or MHF4 plug (female socket) on 216 mm (8.5 in.) coaxial cable.

Ø10.8 mm (0.43 in) Figure 2.  ANT-2.4-WRT-MON Series Antenna Recommended Enclosure Mounting Dimensions Ground Plane 1/4-Wave monopole antennas require an associated ground plane counterpoise for proper operation. The size and location of the ground plane relative to the antenna will affect the overall performance of the antenna in the final design. When used in conjunction with a ground plane smaller than that used to tune the antenna, the center frequency typically will shift higher in frequency and the bandwidth will decrease. The CAP will also affect the final performance. proximity of other circuit elements and packaging nearANTENNA the antenna 7/16-28 UNEF METALIC MOUNTING SHAFT For further discussion and guidance on the importance2.54 of the ground THREADED plane counterpoise, please refer to .100 Linx Application Note, AN-00501: Understanding Antenna Specifications and Operation.

VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna.
