Chip Antennas
A chip antenna is a compact-sized antenna that can transmit and receive high frequency electromagnetic waves. This antenna is suitable for applications where space is limited. Typical applications include mobile phones, Wi-Fi routers, wearable devices, Bluetooth devices, RFID, and NFC. The small size enables them to be mounted on platforms such as printed circuit boards (PCBs).
Selecting Chip Antennas
When selecting a chip antenna, it is important to know the parameters that you need to specify. Below is a list of the key parameters to look out for when selecting this antenna:
Frequency: This is the frequency range over which the antenna can operate.
Gain: It is the ratio of the power delivered in the desired direction to the power radiated equally in all the directions from an isotropic antenna.
Efficiency: It is the ratio of power radiated by the antenna to the power supplied to the antenna.
Type of Polarization: It is the orientation of the electric field radiated from the antenna with respect to the antenna axis. Different polarization types exist, such as linear, circular, RHCP, LHCP etc.
VSWR: It is the ratio of the amount of power reflected back to the input to the incident power. This parameter is represented as 2:1, 4:1, 5.6:1 etc. Generally, the more the VSWR, the higher the reflected power, and the lower the antenna performance.
Mounting Types: Ceramic antennas are available in several mounting types such as surface mount, through-hole, screw mount, PCB mount, thread mount, and adhesive mount.
everything RF has listed several chip antennas from the leading companies. You can compare products, view their specifications, narrow down on products based on the frequency range, gain, polarization, VSWR, and other parameters. Once you find products that you need you can view product specs, download datasheets, request a quotation or more information on a product. Your inquiry will be sent to the manufacturer who will get back to you with the required information.
