Antennas
- Dipole: Balanced, omnidirectional, λ/2 length
- Monopole: Requires ground plane, λ/4 length, omnidirectional
- Yagi-Uda: Directional, high gain, multiple elements
- Parabolic: High gain, directional, reflector-based
- PCB Trace: Integrated, low profile, for RF modules
- PIFA: Low profile, used in mobile devices
- Helical: Circular polarization, used in satellite comms
Key Parameters: Gain (dBi), Impedance (50Ω typical), VSWR (<2:1), Frequency Band
