Modulation Index H = 1, Link Budget Improved compared to 500 kbps data rate, assuming antenna gain is 0 dBi. 2. The RF range calculator is used in the above range estimation. Refer to the RF range calculator under Tool tab at http://www.silabs.com/products/wireless/EZRadioPRO/Pages/Si...
Antenna Gain in dB Antenna frequency (MHz) Outputs Antenna efficiency (%) Here’s how to use the calculator:INPUTS:Antenna diameter = 2.4 meters Antenna Gain (dBi) = 43 Antenna frequency = 6000 MHzOUTPUT:Antenna efficiency = 87.75 % Antenna...
Please refer to coplanar wave guide calculator in Appendix B for the calculation of width for Coplanar transmission line. The bandwidth (S11 ≤–10 dB) of the IFA is 220 MHz around 2.44 GHz, as shown in Figure 17. Figure 17. S11 of the IFA (Return Loss = -S11) Fig...
But when using db gain to rate an antenna you must know what the reference antenna is! It is important to note that antennas are passive, they do not “amplify” signals (or effect transmitted audio levels!), they merely re-distribute the power that they get to achieve gain. They have...
The measured peak gain is 4.95 dB at 3 GHz and 4.88 dB at 2.95 GHz. The Working of Patch microstrip Antenna patch antenna array design A patch antenna radiates as a wide, open half-wave microstrip resonator, and it consists of many individual patches arranged on a dielectric substrate. ...
A dipole antenna has 2.14 dB higher gain than the 0 dBi dipole reference. If antenna gain is given in dBd, not dBi, add 2.14 to convert to the dBi rating. NEED TO KNOW … RF POWER There are several basic rules that you should know when working with antennas, RF power, and expected...
