Text of the note

Shannon's Capacity Theorem

kanal kapasitesi :] kanalın genişliği (Hz)

signal to noise ratio (P_sP_n)

Bit error rate

C → kanal kapasite BG

RF ışıma yapar, anten çalıştığı bölgeye göre tasarlanmış olmalı.

Gürültüyü minimalize etmeliyiz.

RF: 3khz frekansından 300 GHz'e kadar olan tüm sinyaller. (100 GHz üstü milimeter wave, 10 GHz üstü microwave)

frekans büyüdükçe anten küçülür.

White Noise Thermal Noise (Shot Noise) [ → White Noise N(m_0,σ) ]

Flicker Noise (1f^n noise) Pink noise

[SNR] birimi: bel

Log-periodic Antenna her iki alır

metal reflektör koyarsanız sadece tek yönlü olur

Aktif komponentler akımı yön veriyor.

N_A → Filtrenin kendisinden kaynaklanan ek gürültü N_A <<< seçilmeli

Low noise coming from device ( ⇒ low NF) → Noise Figure

Linearity ( ⇒ high P_1 dB → 1dB Compression Point

IP3 → Third order Intercept Point)

Low Power Consumption

Low Area '' (Small form factor)

Matching to anten filter
