The Joymax ISD-S008SMDG antenna is an embedded, surface-mount, helical monopole antenna designed for use in 2400 MHz to 2500 MHz frequency band supporting Bluetooth®, ZigBee®, Thread®, IEEE 802.15.4, IEEE 802.11b/g and other unlicensed ISM application in the 2.4GHz frequency range.
The board-attached spring antenna provides omnidirectional radiation which perfectly matches a portable device, and features low-cost, compact package and low profile to be directly mounted on the main PCB of end-products. Connection is made to the radio through microstrip transmission lines.
