3g microcontroller antenna This article describes the Microchip's 3G Antenna Technology (74HC164). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: 74HC164.

Taoglas Limited the leading provider of antenna solutions to the M2M market, announced today a Wireless Design Partnership agreement with Microchip Technology Inc. Surface-mount technology antennas such as Taoglas’ PA.25 Cellular (2G/3G/3.5G) andSGP.25DGPSpatch are just two of the antennas chosen. Microchip also selected Taoglas’ automotive-approved “Titan” AA.105 Active ExternalGPSIP67 antenna, for customers looking for an external antenna solution.

“After speaking with wireless-module partners and testing the antenna technology ourselves, we are pleased to select Taoglas as an Antenna Design partner,” said Cheri Keller, Microchip’s senior manager, Worldwide Design Partner Program.

“We are excited to partner with a quality organization like Microchip,” said Tim Dolan, North American Sales Manager with Taoglas. “We are the market leader in antennas for wireless M2M applications. With the investments both companies are making in next-generation wireless solutions, and the synergies between the two organizations, together we make a powerful solutions choice for wireless M2M.”

Taoglas CellularSMTAntennas

Taoglas’ ceramicSMTantennas deliver the highest efficiency for a given ground-plane area, without the loss associated with traditional cabled solutions. They eliminate the need for tooling andNREfees. This means the range is available “off the shelf” at any quantity, delivered on tape and reel. All that is needed is for the customer to place the antenna on one of the short ends of their main device board and design a straight 50 OhmCPWtransmission line direct to the module. Tuning of the matching circuit by way of changing simple component values may be necessary. These features allow the antennas to be tuned on the customer side, during integration, and speed up the design cycle dramatically.

Taoglas’ Embedded and Non-EmbeddedGPSAntenna

Taoglas’ uniqueSMTGPSpatches are designed to meet the requirements of high-volume applications that need to avoid manual assembly processes. Again, a shortCPWfrom a surface-mounted module is all that is needed. These newSMTGPSpatch solutions are the first to fully meet the environmental requirements of the automotive industry for temperature, shock, vibration, etc. Taoglas’ design keeps the feedline of theSMTGPSpatch antenna off the side of the ceramic and unexposed, preventing the cracking associated with traditional methods. It also uses a separatePCBto connect to theGPSmodule feedline, along with mechanical pads, for stable integration. Additionally, Taoglas offers further tuning of the patch antenna for different ground-planes.
