GSM Antennas and Their Uses

Posted on by

What Is A GSM Antenna?

An antenna is an electrical device which converts electrical currents into radio waves and vice versa. It is an essential part of a radio allowing a radio frequency (RF) signal generated by a radio device to be sent or received on a particular frequency or frequencies. A GSM antenna can operate on 824-894 MHz, 890-960MHz, 1710-1880MHz and 1850-1990MHz. Often, antennas can operate on more than one frequency range. In this case they are often referred to as dual band (2 frequencies), tri band (3 frequencies) or quad band (4 frequencies).

 

Why Do I Need An Antenna?

The GSM antenna receives or transmits the RF signal – without it the radio system will not work. Antennas are used in all systems using wireless equipment such as key fobs for cars, garage door entry systems, RFID tags, baby monitors and mobile phones.

 

How Does A GSM Antenna Work?

An antenna is made using a conductive strip or wire usually made of metal. This allows an electrical current to pass through which creates a magnetic current. Depending on the frequency, this will create a wavelength which is a certain size. The lower the frequency the longer the wavelength and this will make a GSM signal transmits further.

 

What Should I Look For In An Antenna?

Antennas come in different shapes and sizes and depend on how they are being used. Firstly however, they radiate in 2 ways. The first is the more common – OMNI directional antenna. This allows a 360° radiation pattern so as to transmit and receive in any direction in a circular pattern. Directional antennas transmit and receive RF signals in a limited direction and need to point in the general direction of the other radio.

 

As examples, an antenna on a walkie talkie would be OMNI directional, giving an all-round coverage. A TV antenna mounted on the roof of a house is a Yagi antenna which is directional – pointing in the direction of a TV transmitting power. This allows a concentration of signal to be sent or received.

 

How Many Types Of GSM Antennas Are There?

 

Once an OMNI directional or directional antenna has been determined, there are 6 generally accepted styles of GSM antenna. These depend on the use.

 

  • Embedded antennas are used for when the antenna is being fitted inside equipment.
  • Through hole mount antennas are used in permanent installations and fit via a mounting bolt.
  • Magnetic mount antennas are usually reserved for temporary installations or in evaluation kits.
  • Direct connect antennas screw directly to GSM modems or the back of GSM terminal equipment. External or base station mount GSM antennas often fit on walls and are used in remote locations
  • For wireless telemetry or alarm panel installations.
  • Adhesive mount antennas stick onto glass or other nonmetallic surfaces.

Information of Chip Antenna

Posted on by

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 Wi-Fi routers.

 

Chip antennas radiate and receive electromagnetic waves as do regular antenna, but their most notable difference is their small size. This means they can often be internalized within small electronic devices; they are also inexpensive considering their quality. Chip antennas are the best alternative when a larger-sized antenna is impractical.

 

One means of creating an antenna which can be integrated into a PCB would be the use of fractal geometry. A fractal is a complex pattern constructed from the repetition of a simple shape which maximizes the length or increases the perimeter of the material that radiates an electromagnetic signal. These antennas must be in proportion to the signal wavelength, and the fractal must retain at least two different ratios of the pattern. These antennas can be customized into a variety of footprints and are becoming increasingly common in mobile electronics. Overall, the gain and bandwidth of fractal antennas is exceptional. Fractal antenna designs do not require any additional components to work, which further enables their flexibility.

 

Applications of chip antenna are utilized across a breadth of telecommunications products. This includes: PC peripherals, cell phones, PDAs, tablet computers, portable televisions, satellite radio, headsets, USB dongles, GPS devices, and Wi-Fi and WLAN routers.
