RF Category

The Taoglas ISA.05 adhesive mounted antenna is designed primarily for 915 MHz ISM Band compact wireless applications where it may or may not be attached to metal. When placed on a reference 300 mm square ground-plane, the antenna has an excellent directional hemispherical radiation pattern, high peak gain of 5 dBi at zenith, and an efficiency of 68%. Even without a ground-plane underneath, the antenna achieves 0 dBi and an efficiency of 45%.

The antenna is IP65 water-resistant and comes standard with a microcoaxial cable with 1.37 mm diameter and IPEX MHFHT connector. The Taoglas ISA.05 is an excellent solution for the following applications:

  • Environments where there are lots of metal objects that it may be mounted to (such as near a car engine)
  • RFID Readers
  • Short range 915 MHz mesh networks
  • ISM based IoT protocols such as LoRa and Sigfox.

Cable type, length, and connector can be customised. Mechanical customisation of the antenna can also be done for a minimum order quantity.

The model states a VSWR <6.0:1 for the entire 902 to 928 MHz band, however achieves <2.0:1 at 915 MHz. All specifications are taken using a 300 x 300 mm metal ground plane. Please consult product datasheet for free space performance.

  • Finely tuned for 915 MHz ISM
  • IP65, lightweight heatshrink PCB construction
  • High efficiency on ground plane
  • High gain on ground plane, 0 dBi in free space
  • 300 mm microcoaxial cable with IPEX MHFHT (U.FL) connector
  • Fully customisable cable length and connector
