Reading an Antenna as an RF Port

Question I started with

Rather than memorize the whole transceiver, I isolated the inputs, outputs, and role of Reading an Antenna as an RF Port.

Reading an Antenna as an RF Port — concept flow — I redrew the relationships before returning to the equations.

Connecting the concepts

The key is treating input match, efficiency, gain, and polarization as separate metrics. Frequency, impedance, gain/loss, noise, and linearity at both sides are recorded before connecting the block.

signal chain

Equations and assumptions

I write the reference impedance, units, and linear-versus-decibel domain before substituting numbers.

G = eta DP_rad = eta P_accepted

Worked example

With 10 dBi directivity and 70% efficiency, gain is about 8.45 dBi.

Reading an Antenna as an RF Port — calculation relationship — This is my explanatory redraw, not an imported RFDH figure or a measurement result.

Connecting it to my coursework and projects

I connect this block to my passive-network coursework and FMCW transceiver flow. The example is a recomputed study value, not a hardware measurement.

What I will check next

I do not mix typical, guaranteed, and simulated conditions or directly compare values taken at different frequency, bias, temperature, power, or terminations.
