Bluetooth Radio Module with Embedded Antenna Diversity
نویسندگان
چکیده
— A complete Bluetooth radio module/SiP (System-in-Package) is presented that includes antenna diversity requiring only one external antenna. The module measures only 140 ÑÑ ¾ and has an on-board diversity switch and an embedded antenna. The measured Bit-Error-Rate with and without diversity is presented for a typical indoor environment. It is shown that with the diversity radio module a diversity gain of approx. 8 dB can be obtained for an indoor Bluetooth connection.

In this article, a system-on-package (SoP) approach for Bluetooth system module applications using low-temperature co-fired ceramic (LTCC) technology is presented. The developed LTCC integrated substrate for our Bluetooth module application is overall 12 12 1 mm in size, with integration of two originally proposed components, a balanced-to-unbalanced bandpass filter and a folded meander-line in...
متن کاملFPGA Implementation of MIMO Module
Radio transmissions traditionally use one antenna at the transmitter and one antenna at the receiver. This system is termed Single Input Single Output (SISO). Both the transmitter and the receiver have one RF chain (that's coder and modulator). SISO is relatively simple and cheap to implement and it has been used age long since the birth of radio technology. It is used in radio and TV broadcast...
متن کاملPolyPoint: High-Precision Indoor Localization with UWB
We demonstrate PolyPoint, a high-fidelity RF-based indoor localization system that achieves 28 cm accuracy indoors and tracks a fast-moving quadcopter with only 56 cm average error. PolyPoint uses ultra-wideband signals to achieve high precision RF time-of-flight estimates between nodes. To further improve accuracy, PolyPoint exploits two forms of diversity: frequency diversity, which leverages...

متن کاملFully 3D Printed 2.4 GHz Bluetooth/Wi-Fi Antenna
3D printing and printed electronics are combined to demonstrate the feasibility of printing electrically functional RF devices. A combined process is used to demonstrate the feasibility of fabricating a 2.4 GHz antenna in a fully-3D printed object. Both dielectric, which also serves as the structure, and conductors are printed. Full-wave models are generated using Ansoft HFSS. Real-world tests ...
