TDK Corp. has launched a surface mount ceramic chip antenna for UWB applications. The ANT1085-4R1-01A offers enhanced in-band impedance matching stability allowing for smaller board dimensions, reduced part count and easier circuit layout.

The ANT1085-4R1-01A is a broadband antenna, achieving VSWR below 3:1 across the entire low-band UWB frequency range (3.1-5.2GHz) and has been specifically designed with ease of integration in mind. The antenna's structure allows for a reduced ground plane dependency as well as a smaller PCB keep-out area for components and ground plane, enabling a more compact end-product design. Over 100MHz margin at the upper and lower band edges eliminates the need for board-specific impedance matching.

For optimal performance in mobile applications, the ANT1085-4R1-01A achieves class-leading pattern average gain across the frequency band. It also exceeds the performance of a number of existing UWB antennas in low-band applications, according to an independent survey.

The ANT1085-4R1-01A UWB ceramic chip antenna measures 10mm x 8.5mm, with a low profile of 1.2mm, and requires no dedicated external components. It is available immediately in tape and reel with standard packaging quantities 1,500 pieces/reel. Sample quantities are also available on request.
