What is trace antenna?
What is trace antenna?
The trace antenna is embedded into the PCB board during the manufacturing process. When optimally tuned, a trace antenna can operate within a wide bandwidth while commanding a high level of network reliability and strength. Trace Antennas have a thin profile.
What is PCB antenna?
In telecommunication, a microstrip antenna (also known as a printed antenna) usually means an antenna fabricated using photolithographic techniques on a printed circuit board (PCB). It is a kind of internal antenna. They are mostly used at microwave frequencies.
Which antenna is used in GSM?
GSM Antenna is one kind of Antenna to transmit GSM signal at specified frequency 850, 900, 1800, 1900, 2100MHz. 2100MHz is separated into UMTS (Universal Mobile Telecommunications System) frequency band for 3G, and other frequencies are separated into 2G. GSM Coverage Maps and Roaming Information.
How does a PCB trace antenna work?
PCB antenna is a transducer converting current waves into electromagnetic (EM) waves in a high-frequency PCB. PCB antennas convert current in high frequency into EM waves that propagate into the air. There are two PCB antennas in a high-frequency PCB. They are embedded into the PCB as the etched copper structure.
How is PCB antenna calculated?
Wavelength, Frequency, and Length of an Antenna T=1/f Where T = Time F = frequency So, for an antenna, operating at 50MHz, t =1/f = 0.2uS, And the wavelength (λ) = C/f = 3*10^8 / 50*10^6 = 6m Where, C is the speed of light.
What is FPC antenna?
Flexible Printed Circuit Board Antennas, or FCB Antennas are flexible, low profile, highly reliable and economical antennas that are widely used in the wireless industry. A FCB antenna usually consists of polyimide flexible PCB, with a patterned conductive (mostly copper) material for the desired antenna topology.

What is LDS antenna?
Laser Direct Structuring (LDS) is a process whereby an antenna can be designed and produced onto a 3-dimensional plastic carrier. This carrier can be a separate plastic entity or an existing integral part of the customer’s product’s housing.
What is flex antenna?
Flex circuit antennas or flexible circuit boards are designed in a flexible material with a square form-factor and cable connection for easy. installation.
How do I identify an antenna?
Certain basic characteristics of antenna are listed below:
- Antenna Radiation Pattern.
- Radiation Intensity.
- Directivity and Gain.
- Radiation Efficiency and Power Gain.
- Input Impedance.
- Effective Length.
- Effective Aperture.
How long is a 2.4 Ghz antenna?
The length of the antenna on a typical 2.4GHz receiver is 28.8 to 32 mm long, most are about 28.8 mm. The antenna is that length of bare line often at the end of a longer coaxial cable to move the antenna farther out from the receiver.
What is basic antenna parameters?
Typical parameters of antennas are gain, bandwidth, radiation pattern, beamwidth, polarization, and impedance. The antenna pattern is the response of the antenna to a plane wave incident from a given direction or the relative power density of the wave transmitted by the antenna in a given direction.
What is antenna gain formula?
The gain of an antenna G = Antenna efficiency * Antenna directivity D. Units for Gain – dB (decibels), dBi (decibels relative to an isotropic antenna), dBd (decibels relative to dipole antenna)
What is LDS material?
Laser Direct Structuring (LDS) The LDS process uses a thermoplastic material, doped with a (non-conductive) metallic inorganic compound activated by means of laser. The basic component is single-component injection molded, with practically no restrictions in terms of 3D design freedom.
Which are the two basic types of antennas?
There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional. – Omni-directional antennas propagate in all directions. – Semi-directional antennas propagate in a constricted fashion, defined by a specific angle.
What is the range of GSM?
Frequency Band The uplink frequency range specified for GSM is 933 – 960 MHz (basic 900 MHz band only). The downlink frequency band 890 – 915 MHz (basic 900 MHz band only).
What are GSM standards?
The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.
What is GSM channel structure?
GSM Channel are divided into two types: Traffic channels (TCHs): The traffic channes are intended to carry encoded speech or user data. Traffic channels are intended to carry encoded speech and user data. Full rate traffic channels at a net bit rate of 22.8 Kb/s (TCH/F)
What type of trace antenna should I Choose?
PCB trace antennas are a good compromise between performance, repeatability, size, and cost. They are easy to tune. We will cover tuning later on. SMA connector to external whip antenna (not covered in this guide) External whip antennas (also known as ducky antennas) are typically a bit larger, but are a good choice if you have the room.
How do I test my antenna design?
Size the feedline for your application Test the antenna with an SMA connector and a spectrum analyzer, if possible. (in your enclosure if you’re using one) Use your testing results to correct your design There are a lot of good ones out there.
How to match the material of antenna to design?
Duplicate it precisely in your design. Even the position of vias around the antenna and the thickness of the copper layers (1 oz vs 2 oz) can make a difference, but if you match the material and overall thickness you should be ok.
How do you measure antenna power loss?
Power loss is one way to look at our antenna, but another common method to visualize the parameters of an antenna is called a Smith Chart . Here is an example of a big scary looking smith chart:
