The Joymax URD-C020SMDB antenna is an embedded, surface-mount, helical monopole antennas designed for use in 433 MHz band supporting ISM and low-power, short-range application e.g. remote controls, smart sensors.
The board-attached antenna provides omnidirectional radiation which perfectly matches a portable device, and features compact package and low profile to be directly mounted on the main board of the end-products. Connection is made to the radio through microstrip transmission lines.
