Antennas are devices used for the transmission of radio waves, for television, radio, mobile phones and other equipment. RS offer a great range of antenna components, equipment and supplies that can be used for a wide range of applications.
Antennas are available in various forms, each designed to cater to specific communication needs and frequency ranges. Let's delve into the distinctive characteristics of several common antenna types.
Aerial antennas, commonly installed outdoors on rooftops or buildings, specialise in capturing over-the-air signals, particularly for television and FM radio broadcasts. Their strategic placement optimises signal reception, making them crucial for both residential and commercial broadcast environments.
Radio antennas serve as the conduit for transmitting and receiving radio frequency signals across various applications, including AM/FM broadcasting, two-way communication systems, and specialised uses like GSM and GPRS. These antennas play a vital role in ensuring reliable communication across different frequency bands and environments.
GPS antennas can receive and/ or expand the distance of RF (radio frequency) signals from GPS satellites. The antennas then convert the frequencies into electronic signals so they can be used with GPS receivers.
GSM Antennas are optimised for the transmission and receiving of radio signals across the various mobile communication bands. GSM Antennas are often used with a GSM and GPRS Modem or an RF Module to connect remote equipment back to a central server.
Multi-band antennas are designed to work within more than one frequency band. The antennas have an active part for specific frequencies and the other active part for alternative bands. Multi-band antennas can be used on VHF and UHF frequencies.
Radio Frequency Identification Antennas are used for wireless systems. RFID antennas transmit power to RFID tags and receive the data back from the triggered tags. RFID antennas are controlled by the RFID reader.
SMT antennas are specifically designed to be mounted onto a PCB board. SMT antennas radiate high-frequency electromagnetic waves. Compact in design SMT antennas work exactly like a normal antenna but usually have a limited range.
Used to record and transmit data from remote sources back to IT systems. Telemetry antennas are used along with transmitters and receivers in a wide range of applications across many industries.
These antennas are designed to pick up the wireless network radio transmissions that are broadcast from devices including mobile phones, laptops and routers. WiFi antennas are used for the enhancement of signals and can give you better range and performance.
The radiating element serves as the core of an antenna, responsible for converting electrical signals into electromagnetic waves for transmission or vice-versa for reception. It can manifest in various forms, including dipoles, monopoles, patches, or helixes, tailored to the specific antenna type and frequency range.
The feed line acts as the conduit between the antenna and the transmitter or receiver, carrying electrical signals to and from the radiating element. The choice of the feed line, whether it's a coaxial cable, waveguide, or microstrip line, is contingent upon factors such as frequency and power level.
The ground plane establishes a reference point for the antenna's operation, influencing its radiation pattern and impedance. It can be a physical ground plane, such as a metal sheet or the Earth's surface, or a virtual ground plane created by other conductive elements within the antenna structure.
The matching network ensures optimal power transfer between the feed line and the antenna by achieving an impedance match. It can be a simple transformer, a complex network of inductors and capacitors, or even integrated into the antenna's design itself.
Antennas play a pivotal role in a wide array of industrial applications, enabling wireless communication and sensing across various sectors. Here are some illustrative examples:
