I make slot antennas for all frequencies from 23cm to 24ghz and all frequencies in between hams bands

Some points about 2.4Ghz coaxial cable antenna for routers and Robotics Vehicles: Radio equipment using the license-free 2.4-GHz ISM

Cutting the 3mm slots in the coax cable. Remove the 8 mm copper sheath entirely and flatten it,then trim it to a width of 20mm, and then cut in half for 2x 10 mm widths

5.6dBd gain flat VSWR and good gain bandwidth performance over the entire 420-440 MHz band

E' possibile utilizzare barattoli di provenienza alimentare con diametri compresi fra 75 mm e 85 mm, misure che garantiscono il massimo rendimento nella zona dei 2.4 GHz

Antenna slot usata per i ripetitori in FM, polarizzata in orizzontale

L'alford entra la risuonare sulla frequenza stabilita 1.240 Mgz, l'antenna e' stata misurata con strumenti adatti per la radio frequenza

Slot antenna and complementary dipole, it is shown that on condition of inverting the E and H fields

L'antenna Corner Reflector è costituita da un riflettore a V e da un dipolo

The waveguideslotted object creates a slotted waveguide antenna. there are different types of slotted waveguid

Slot antennas are popular omnidirectional microwave antennas

H polarisation, slot only on 1 side 360 deg coverage +/- 3dB

The slot antenna consists of a radiator formed by cutting a narrow slot in a large metal surface

But microwave equipment has been steadily penetrating into mainstream applications. Microwave ovens operating at 2.4GHz have already been with us for several decades
