Return Loss
A line graph plotting Return Loss (S(dB)) against Frequency (GHz) from 2.0 GHz to 3.0 GHz. The graph shows three data points labeled M01, M02, and M03 corresponding to frequencies 2.400 GHz, 2.442 GHz, and 2.484 GHz respectively, with values around -17 dB to -19 dB.
- 2.400 GHz: S(dB) -17.369, S(VSWR) 1.313
- 2.442 GHz: S(dB) -18.666, S(VSWR) 1.264
- 2.484 GHz: S(dB) -16.704, S(VSWR) 1.342
VSWR
A line graph plotting VSWR against Frequency (GHz) from 2.0 GHz to 3.0 GHz. The graph shows three data points labeled M01, M02, and M03 corresponding to frequencies 2.400 GHz, 2.442 GHz, and 2.484 GHz respectively, with values around 1.2 to 1.4.
Efficiency and Directivity
The document presents detailed efficiency and directivity measurements across different planes (XY, YZ, ZX) and polarizations (horizontal/veritical) for frequencies 2400 MHz, 2442 MHz, and 2484 MHz. Key values include:
- 2400 MHz: Peak gain in XY-plane (hor: -11.4 dBi, ver: -2.8 dBi), YZ-plane (hor: -21.8 dBi, ver: -2.8 dBi), ZX-plane (hor: -7.6 dBi). Total Efficiency (AVE): -4.5 dB (35.7%).
- 2442 MHz: Peak gain in XY-plane (hor: -11.6 dBi, ver: -2.7 dBi), YZ-plane (hor: -23.3 dBi, ver: -2.7 dBi), ZX-plane (hor: -7.7 dBi). Total Efficiency (AVE): -4.5 dB (35.7%).
- 2484 MHz: Peak gain in XY-plane (hor: -11.5 dBi, ver: -2.8 dBi), YZ-plane (hor: -24.9 dBi, ver: -2.8 dBi), ZX-plane (hor: -7.8 dBi). Total Efficiency (AVE): -4.5 dB (35.7%).
Average values for efficiency are similar across frequencies. The note "Red color shows peak gain" is associated with the directivity plots.
Directivity Plots: Polar plots illustrate antenna directivity and efficiency across different planes (XY, YZ, ZX) at specific frequencies (2400 MHz, 2442 MHz, 2484 MHz). These plots show the radiation pattern of the antenna, with color indicating signal strength or gain.
