10 Electrical Parameters Center frequency Bandwidth VSWR Return Loss Gain Efficiency

11 Terms and Descriptions Directivity We have seen that standard antennas emit more radiation in some directions than in others. Indeed, it is topologically impossible for an antenna to emit waves uniformly in all directions. We use directional pattern to identify the directivity. Center frequency There are many values of center frequency for Sunlord s chip Bluetooth antenna, such as 2.54GHz, 2.64GHz, 2.66GHz, 2.71GHz, etc. Range is ± 30MHz frequency. Greater frequency diversity will better meet customer needs.

12 Terms and Descriptions Bandwidth It is the frequency range to ensure electrical characteristic within the SPEC. VSWR VSWR (Voltage Standing Wave Ratio or, occasionally, Vertical Standing Wave Ratio), is a measure of how efficiently radio-frequency power is transmitted from a power source, through a transmission line, into a load (for example, from a power amplifier through a transmission line, to an antenna). It is calculated by the following formula. VSWR = (1+Γ)/(1-Γ) Γ (gamma) is the voltage reflection coefficient near the load. The value of VSWR is between 1 and infinity. If the load and transmission line are matched, Γ= 0, and VSWR = 1; If completely mismatched, VSWR is infinity.

13 Terms and Descriptions Return loss The Return Loss of a line is the ratio of the power reflected back from the line to the power transmitted to the line and measurement of return loss can reveal line faults due to mismatching. It is calculated by the following formula. Return Loss=20log( Γ ) Γ (gamma) is the voltage reflection coefficient near the load. For maximum power transfer the return power should be as small as possible. This means that when expressed in db, the return loss should be as large a negative number as possible. For example a return loss of -40dB is better than one of -20dB. Gain It stands for the ability of antenna to emit/receive signals to/from a particular direction. It can be measured by antenna s input and output power amplification. The higher the gain is, the further distance radio wave radiates. Efficiency Antenna efficiency is defined as the ratio of the total power radiated into space to the total power at the input port.

17 Chip Antenna Selection - Based on the size of the antenna pad - Notice the physical environment of PCB - Larger size antenna will make better performance if the space is enough. - Choosing suitable frequency for antenna

22 Terms and Descriptions Center Frequency(Fo) Usually defined as the midpoint frequency between 3dB frequency range of a band pass filter or stop filter. Insertion Loss (IL) Insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line and is usually expressed in db. If the power transmitted to the load before insertion is PT and the power received by the load after insertion is PR, then the insertion loss in db is given by Attenuation It shows the signal loss of stop band.
