WDMP.2458.A Embedded Dual-Band Wi-Fi Circular Polarized 50*50mm Patch Antenna Datasheet

PublishTime：2020-07-16

The WDMP.2458.A antenna with SMA(F) connector is a circular polarized dual-band Wi-Fi antennaalso covering the 7.1GHz Wi-Fi 6 bandwhich consists of an advanced composite dielectric structure, providing better performance at greater distance and a broader band frequency range in the smallest package in the market.Using military grade substrates, the WDMP.2458.Ais aimed at unmanned systems, such as unmanned aerial/ground vehicles (UAVs/UGVs), robotics, and ground controllers/stations, applicable in different sectors from civilian, law enforcement, to defence.Taking advantage of substrates of low dielectric constant and low dissipation factor, the WDMP.2458.A uses glass microfiber reinforced PTFE substrates to minimize signal transmission loss in order to achieve high efficiency. It performs with high efficiencies at Wi-Fi bands from 2400~2500MHz, 5150~5850MHzand 5925~7125MHz. Using circular polarized signals means the link is more stable for devices where the direction of orientation is unknown or where multipath is an issue.The WDMP.2458.A’s low profile design, equipped with a SMA(F) connector, is easy to install inside a housing or directly onto a PCB mainboard. It has four thru-holes at the patch corners, allowing users to fix the antenna with screws. The antenna has passed ISO 16750 high/low-temperature test and random vibration reliability testing.Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Those peak gain limits are based on free-space conditions. In practice, the peak gain of an antenna tested in free-space can degrade by at least 1 or 2dBi when put inside a device. So ideally you should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect, giving you better performance.Upon testing of any of our antennas with your device and a selection of appropriate layout, integration technique, or cable, Taoglas can make sure any of our antennas’ peak gain will be below the peak gain limits. Taoglas can then issue a specification and/or report for the selected antenna in your device that will clearly show it complying with the peak gain limits, so you can be assured you are meeting regulatory requirements for that module.For example, a module manufacturer may state that the antenna must have less than 2dBi peak gain, but you don’t need to select an embedded antenna that has a peak gain of less than 2dBi in free-space. This will give you a less optimized solution. In that case it will be better to go for a slightly higher free-space peak gain of 3dBi or more if available. Once that antenna gets integrated into your device, performance will degrade below this 2dBi peak gain due to the effects of GND plane, surrounding components, and device housing. If you want to be absolutely sure, contact Taoglas and we will test. Choosing a Taoglas antenna with a higher peak gain than what is specified by the module manufacturer and enlisting our help will ensure you are getting the best performance possible without exceeding the peak gain limits.
