Bluetooth Antenna with 3dBi Gain
Korean manufacturer AMOTECH has developed small surface mountable ceramic antennas with 3 dBi gain for use in Bluetooth and other 2.4 GHz applications where small size and low weight are key factors. AMOTECH provides 3 kinds of antennas with different dimensions: 8 × 8 × 3 mm, 6 × 4 × 3 mm und 6 × 4 × 2 mm. Internal antenna mounting eliminates the risk of antenna damage while offering comparable electrical performance to external antennas. The proprietary dielectric material used provides for an incorporated filtering function. The antennas are omni-directional towards the azimuth and have a 150 MHz bandwidth. Their characteristics are less dependent on ground plane size and can be supplied in modifications for specific circuits.
