Aperture Antennas (1)

A narrow slot cut in a conducting sheet that radiates like a complementary dipole.

Several in-line radiators stacked to squash the pattern toward the horizon.

Two crossed dipoles fed in quadrature for circular or omnidirectional coverage.

A tower beside the runway that projects the correct descent angle using ground reflection.

The long flat 'hockey-stick' array atop the radar that interrogates aircraft transponders.

A directional, extremely broadband array of progressively scaled dipoles.

A coil of wire about a wavelength around that radiates a circularly polarized beam.

A short, coiled flexible antenna that fits a quarter-wave into a stubby package.

A flat metal patch printed on a dielectric board that radiates broadside.

A folded, shorted patch that fits an efficient antenna into a tiny device.

A dipole in front of a V-shaped reflector for moderate, simple gain.

A disc-over-cone vertical with enormous bandwidth and an omnidirectional pattern.

A quarter-wave vertical with radials that form an artificial ground.

🔧 Buildable at home

An end-fed half-wave vertical matched by a quarter-wave parallel stub.

🔧 Buildable at home

A dipole with triangular flared elements for wideband, often UHF, use.
