868 and 915 MHz PCB AntennaDesign Note DN008 868 MHz and 915 MHz PCB Antenna By Audun Andersen Keywords CC1000 CC1010 CC1020 CC1021 CC1050 CC1070 CC1100 CC1150 PCB Antenna 868 MHz 915 MHz Monopole 1 Introduction mm. Thus this is a medium size, low cost antenna solution. Figure 1 shows a picture the board being used to develop and characterize this antenna. The board is pin compatible with CC1100 EM and can be plugged into SmartRF04EB for test and characterization purpose. This document describes a PCB antenna designed for operation in the 868 MHz and 915 MHz ISM bands. This antenna can be used with all transceivers and transmitters from Texas Instruments, which operates in these frequency bands. Maximum gain is measured to be 4.6 dB and overall size requirements for this antenna is 39 x 37 Figure 1.……
