Molex cellular ceramic antennas

Molex’s compact ceramic cellular antennas support high-performance MIMO applications in telecommunications, industrial and other wide-frequency-band operations. The 146200 series features a bandwidth of 698 MHz to 2.7 GHz, while the 204774 series ranges from 790 MHz to 2.7 GHz. 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.

Features

​SERIES 146200

• ESD-protecting radiation pattern
  • All radiation patterns are directly connected to the system ground to eliminate damage caused by electrostatic discharge
• Indirect-feed design
  • Enables wider impedance bandwidth
• Indicator (“M”)
  • Denotes ‘Mirror-image’ to matching part 146200-0001

SERIES 204774

• Fixing pads
  • Firmly anchor the antenna housing onto the SMT pads of the PCB
• 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
• Feeding pad
  • Ensures electrical signals form a 50-Ohm transmission line on the PCB is fed into the antenna
