In practice, the peak gain of an antenna tested in free-space can degrade by at least 1 or 2dBi when put inside a device. Those peak gain limits are based on free-space conditions. Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Taoglas helps customers fine-tune the antenna for optimal performance through matching, correct board layout, transmission line design, and if necessary, custom antenna tuning for a MOQ. Larger ground-planes increase peak gain and efficiency. Like all small antennas, frequency detuning or efficiency change can occur due to surrounding components and enclosure housing. The SWLP.2450.10.4.A.02 can be placed in any position on the device ground plane. If utilized on a 50*50 ground plane, efficiency will improve to 40% at 2455MHz. The antenna exhibits 24.8% efficiency on a 12*16mm ground plane at 2455 MHz. It provides omni-directional coverage similar to chip antennas on small boards. The antenna also does not need ground plane clearance around it (except for feed area). It was developed specifically for Bluetooth LE wearable applications to work directly on ground (except for feed area) and over metal, device environments which traditional chip antennas cannot operate in.
#Swlp.2450.10.4.a.02 diptrace model Patch
The smallest 2.4GHz patch available worldwide, it is ideally suited for 2.4 GHz applications such as Bluetooth LE, Wi-Fi, ISM, and ZigBee. The SWLP.2450.10.4.A.02 patent-pending 10mm SMT ceramic patch antenna is a breakthrough antenna in terms of size and performance.
