Design of a Size Reduced Antenna Array for Angle of Arrival (AoA) Estimation for BLE 5.1
(2020) EITM01 20201Department of Electrical and Information Technology
- Abstract (Swedish)
- Bluetooth low energy (BLE) 5.1 allows for Angle of Arrival(AoA) measurements
which in turn requires antenna arrays to be used. These arrays must be low power
which results in that an efficient switching pattern is applied and for greater field
of view good omnidirectivity is necessary. BLE devices are typically small in size
and therefore size reduction of these arrays are of interest. The typical spacing
between antennas in arrays are 0.5λ which is around 6 cm and become rather
large. In this thesis a size reduced L-shaped antenna array consisting of three
antenna elements with 0.3λ spacing is simulated. Two major studies were made
with various spacings between 0.25 and 0.5λ, both physical measurements on a
three element... (More) - Bluetooth low energy (BLE) 5.1 allows for Angle of Arrival(AoA) measurements

with various spacings between 0.25 and 0.5λ, both physical measurements on a
three element prototype array and simulations showed that 0.3λ was the smallest
spacing achievable without compromising AoA compatibility. The final simulated
antenna array shows peak gain at 2.55 dB and resonance at 2.44 GHz as well as a
field of view of around 100 degrees. (Less)
