What are PCB antennas used for?
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.
What is a chip antenna?
Chip antennas are a particular type of antenna valued for their small footprint. They are most commonly integrated in circuit boards to radiate high frequency electromagnetic waves. They have a limited range, making them optimal for small devices such as cell phones and WiFi routers.
Why are GPS antennas ceramic?
As the ceramic acts as a gateway for RF signal, the larger the patch, the wider range of bands the antenna can effectively operate on. By contrast, a surface mountable antenna can work effectively on these wide frequency bands.
What is NFC antenna?
The NFC Technology was first introduced into smartphones in September 2011 and is now widely integrated into most phones, whether they are iOS or Android based. An NFC-enabled smartphone uses an NFC controller chip connected to an NFC antenna.
Is chip antenna monopole?
A chip antenna is a quarter wave monopole antenna that works with a printed circuit board (PCB) ground plane to form a dipole system.
How big is an NFC antenna?
NFC transponders come in a variety of sizes and shapes. The transponder dimension is adapted to the defined antenna sizes. The most common antenna sizes are from 19 x 12 mm to 76 x 45 mm.
What is the difference between RP SMA and SMA?
SMA stands for Sub-Miniature Version A. These are coaxial RF connectors developed in the 1960s. RP-SMA stands for Reverse Polarity SMA). It is a variation of the SMA connector which reverses the gender of the interface….Differences of RP-SMA and SMA Antenna Connectors.
| SMA Female | SMA Male |
|---|---|
| RP-SMA Female | RP-SMA Male |
Is IPEX the same as UFL?
U. FL connector is made by Hirose, and is equivalent of IPEX MHF connector. Hirose U. FL cable connector can be terminated with 1.13mm, 1.32mm, 1.37mm, 0.81mm RF cable to be U.
What is the difference between Chip Antenna vs PCB antenna?
Regarding the chip antenna Vs PCB antenna comparison, it will help if you consider a PCB trace antenna when minimizing the entire device cost. On the other hand, Ceramic Chip antennas provide efficient general performance regarding miniaturization and performance. This article digs deep into the chip antenna Vs PCB antenna debate.
What is the length of a PCB antenna?
So, if you do the same calculation for 2.45GHZ, we will get an antenna length of 23mm. Now the basic out of them, we can turn our focus to the main attraction of the blog which is PCB antenna design.
What are the types of PCB trace antenna?
The examples of the types of traces in use for PCB Trace antennas include inverted F-type traces, straight traces, meandered traces, curved traces, or circular traces.. Overall, the purpose of a trace antenna on a PCB is to provide a method of wireless communication.
What determines the size of a PCB antenna patch?
Patch size directly depends on the wavelength of the target operating frequency. PCB antennas mostly discussed are omnidirectional, directional, and semi-directional antennas.
