Specification Part No : ISMP.915.35.6.A.02 Product Name : Embedded ISM 915MHz Ceramic Patch Antenna (35x35x6mm) Provides Compact Directive Pattern Feature : For RFID, LoRA, Sigfox and ISM 915MHz Applications 2dBi peak gain on 70x70mm ground plane 35x35x6mm Ceramic Patch Pin Mount Custom Tuning Optional RoHS Compliant SPE-18-8-065/C/AH Page 1 of 14 1. Introduction ISMP.915 is a low-profile pin-mount ceramic patch antenna operating at 915 MHz. At just 35x35mm, it provides a high-performing antenna solution using minimum board space. When mounted on a 70x70mm ground plane, ISMP.915 provides efficiency of over 75% and peak gain of 2.5 dBi. It is also right-hand circularly polarized, with an excellent axial ratio of less than 3 dB, providing maximum link reliability between devices where the orientation to each other is changing. These characteristics make it a perfect choice for compact fixed wireless applications operating on the 915 MHz ISM band, including remote instrumentation and RFID applications. It also provides excellent performance on Low-Power Wide-Area Networks (LPWAN) operating at 915 MHz, such as LoRa and Sigfox, allowing users to take advantage of the low-power, long-range communications offered by these networks. Like all antennas the ISMP.915 will perform differently subject to nearby device environment and ground-plane changes compared to specification. Taoglas offers custom tuning for specific device environments and ground-planes, subject to NRE and MOQ. Contact your regional Taoglas sales office for these services as well as additional support with device integration. 3D STEP file available for ease of mechanical integration.
