SPECIFICATION Part No. : GW.26.0111.HT Product Name : 2.4GHz Miniature Screw mount Monopole Antenna HIGH TEMPERATURE Feature : SMA(M) Straight Connector, 50 Ohm Dupont(R) Hytrel(R) High Temperature Resistant TPEE Housing (up to 150C) ROHS Compliant SPE-14-8-021/D/PK Page 1 of 11 1 Introduction The GW.26 HT series 2.4 GHz Monopole SMA (M) mount antenna is ideal for 2.4 GHz wireless applications such as Wifi, Zigbee and Bluetooth. Antenna housing is made of highly resistant Dupont(R) Hytrel(R) TPEE material which is durable in high temperature application environments up to 150C. This material is often applied in automotive or industrial applications, where the antenna is placed near the engine or heat generating components. 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. It is 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. Connection is made via a fixed SMA(M) connector with a hardened TPEE casing, this antenna is the ideal Wi-Fi-Bluetooth-ZigBee antenna for M2M devices where the antenna must be placed in harsh high temperature environments. 2 Specification Wi-Fi 2.4GHz Frequency 2400~2500MHz Bandwidth 100MHz SPE-14-8-021/D/PK Page 2 of 11 Peak Gain > 0dBi Radiation Efficiency > 40% Radiation Omni-directional Polarization Vertical Power Handling 1W Max Power Handling 1W Max Electrical Wave Monopole Impedance 50 Operating Temperature -40C ~ +150C Storage Temperature -40C ~ +85C SPE-14-8-021/D/PK Page 3 of 11 3 Mechanical Properties No Parameter Specification 1 Temperature -40c to +150c 2 Radome Colour Black 3 Radome Material Dupont(R) Hytrel(R) TPEE 4 Antenna Characteristics 4.1 Antenna S11 SPE-14-8-021/D/PK Page 4 of 11 4.2 Antenna Peak Gain 3 Peak Gain (dBi) 2 Peak Gain(dBi) 1 0 -1 -2 -3 -4 2350 2360 2370 2380 2390 2400 2410 2420 2430 2440 2450 2460 2470 2480 2490 2500 2510 2520 2530 2540 2550 Freq(MHz) SPE-14-8-021/D/PK Page 5 of 11 4.3 Antenna Efficiency 60 Efficiency (%) 50 Efficiency(%) 40 30 20 10 0 2350 2360 2370 2380 2390 2400 2410 2420 2430 2440 2450 2460 2470 2480 2490 2500 2510 2520 2530 2540 2550 Freq(MHz) SPE-14-8-021/D/PK Page 6 of 11 4.4 Antenna pattern (XY plane) SPE-14-8-021/D/PK Page 7 of 11 4.5 Antenna pattern (XY plane) 0 5 330 30 0 -5 -10 -15 300 60 -20 -25 -30 -35 270 -40 90 2400MHz 2420MHz 2440MHz 240 120 2460MHz 2480MHz 2500MHz 210 150 180 SPE-14-8-021/D/PK Page 8 of 11 4.6 Antenna pattern (XZ plane) 0 0 330 30 -5 -10 -15 300 60 -20 -25 -30 -35 270 -40 90 2400MHz 2420MHz 2440MHz 240 120 2460MHz 2480MHz 2500MHz 210 150 180 SPE-14-8-021/D/PK Page 9 of 11 4.7 Antenna pattern (YZ plane) 0 0 330 30 -5 -10 -15 300 60 -20 -25 -30 -35 270 -40 90 2400MHz 2420MHz 2440MHz 240 120 2460MHz 2480MHz 2500MHz 210 150 180 SPE-14-8-021/D/PK Page 10 of 11 5.
