Hace 5 días · La ganancia de la antena es esencial para: Maximizar el alcance de la comunicación: Las antenas de alta ganancia pueden transmitir y recibir señales a mayores distancias. Reducir los requisitos de potencia: Al enfocar la energía de manera más eficiente, se necesita menos potencia para la transmisión.
Hace 4 días · Most times it means putting your antenna up as high as possible. As a long standing rule of thumb: If you double the height of your antenna you will gain 6 db gain! That means if you had an antenna at 25 feet and decided to put it up on a small tower to 50 feet of height, you'll gain 6 db! That is ALOT.

To measure the beamwidth (-3 dB), front to back ratio, side lobe level and its angular position, plane of polarization and directivity and gain of Dipole Antenna. 2. THEORY.
Hace 2 días · Antenna gain refers to the measure of how much power is transmitted in the direction of peak radiation to that of an isotropic source. How does antenna gain affect ERP? A higher antenna gain increases the ERP, allowing for a stronger signal to be transmitted or received in specific directions.

Hace 2 días · Calculation Formula. The G/T ratio is calculated using the formula: \ [ \text {G/T Ratio (dB/K)} = G - 10 \log_ {10} (T) \] Where: \ (G\) is the antenna gain in decibels (dB). \ (T\) is the system noise temperature in Kelvin (K). Example Calculation. For an antenna with a gain of 38 dB and a system noise temperature of 65,000 K:
