Ceramic Chip Antenna
Mitsubishi Chip Antenna
This document describes an antenna design that can be used with all transceivers and transmitters from Texas Instruments which are capable of operating in the sub 1 GHz bands. The
The AMD series antennas from Mitsubishi Materials Corporation are surface mountable dielectric chip antennas. They can be used in a wide range of frequency by properly selecting matching inductors. They are compact antenna solutions with high performance.
The antenna has been implemented on a CC1101-Q1 EM as shown in Figure 1. All measurement results presented in this document are based on measurements performed on the CC1101-Q1 EM attached to a SmartRF04 evaluation board as shown in Figure 2.
This antenna is available in the CC- Antenna-DK. CC-Antenna-DK board 3 has been tuned to 868 MHz and CC-Antenna- DK board 12 has been tuned to 433 MHz, as shown in Figure 3.
