Half-Wave Dipole Antenna
Half-wave dipole antennas revolutionized radio by perfectly matching antenna length to signal wavelength
5 hours ago
0
Why is the length of a half-wave dipole antenna set to half the wavelength of the target frequency?
To create resonance that maximizes signal radiation and reception efficiency
To minimize the physical size of the antenna regardless of frequency
Because it requires a ground plane to function properly

Half-wave Dipole Antenna
Half-wave dipole antennas create a virtual ground, defying the need for physical grounding
9 Feb 2026
0
Why is the length of a half-wave dipole antenna set to half the wavelength of the signal it transmits or receives?
Because this length allows the antenna to resonate at the signal frequency, maximizing radiation efficiency
Because it minimizes the physical size of the antenna regardless of frequency
Because it matches the length of a monopole antenna for simplicity
