Serial 204774

790 MHz to 2.7 GHz Cellular Ceramic Antennas

Features & Benefits

  • Fixing pads – Firmly anchor the antenna housing onto the SMT pads of the PCB
  • Feeding pad – Ensures electrical signals form a 50-Ohm transmission line on the PCB is fed into the antenna
  • Grounding pad – Ensures the antenna is safely grounded on the application PCB
  • Ceramic antenna housing – High thermal conduction and resistance against detuning effects of environmental interference

Advantages
As these antennas are similar in design and attributes, only one matching circuit is needed when used in MIMO systems. The advantage of this is lower overall application costs. Other advantages include: indirect feed design, leading to improved antenna performance when the phone is held in hand or placed near the user’s body.

Applications

  • Telecommunications/Networking
    • MIMO routers
    • VPN routers
    • Wireless LAN systems
  • Wireless Infrastructure
    • Wireless embedded systems
    • Wireless radio communication equipment
    • MIMO satellite communications (SatCom) systems
