Ceramic Antennas
Ceramic Antennas are compact antennas that are made of ceramic material. Due to their compact size, they can be easily soldered to a PCB. They are functionally similar to other types of antennas – they are capable of transmitting and receiving electromagnetic waves from nearby electronic devices.
The compact size makes them suitable for applications such as IoT devices, smartphones, Wi-Fi routers, Bluetooth devices, and so on.
Selecting Ceramic Antennas
When selecting a ceramic 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 1.2:1, 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, magnetic mount, adhesive mount etc.
everything RF has listed several ceramic antennas from the leading companies. You can compare products, view their specifications, and narrow down on products based on the frequency range, gain, efficiency, 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.
