What is PCB WIFI antenna?
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 MIFA antenna?
2.1 Antenna used in the USB dongle. MIFA is a PCB antenna for low-cost, low-profile, and high-efficiency applications. The meander trace design effectively reduces antenna dimensions and is easily integrated. NXP completed the antenna simulation with the housing removed.
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 a 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 are chip antennas?
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.
What is meander antenna?
A meander antenna is an extension of the basic folded antenna and frequencies much lower than resonances of a single element antenna of the equal length. Radiation efficiency of meander line antenna is good as compare to conventional half and quarter wavelength antennas.
What is a PIFA antenna design?
The Planar Inverted-F antenna (PIFA) is increasingly used in the mobile phone market. The antenna is resonant at a quarter-wavelength (thus reducing the required space needed on the phone), and also typically has good SAR properties. This antenna resembles an inverted F, which explains the PIFA name.
What is trace antenna?
Is a longer antenna better?
It all depends on what your transmitting and receiving frequencies are. Theoretically, a longer antenna will have a greater range, but it is far more important for optimal radio performance that the length of the antenna matches the frequency.
