High Gain 10dBi Panel Patch 5GHz Antenna

[Admin 2705]

Single band IEEE 802.11 a/n standard

High gain patch antenna

Frequency (MHz) : 5150-5825

Peak Gain (dBi) : 10.0

VSWR : 2.0 : 1

Dimension (mm) : 76 x 72 x 3.8

Connector : IPEX MHF I

Cable Length (mm) : 50 (customized)

It seems to work well on the 5.6 GHz frequency.

This is stainless steel or sheet metal? 

[Admin 2705]

,,,,galvanized sheet metal...!

[KSM 11]

I have heard that steel is not good for high-frequency antennas.

[Admin 2705]

What is this?

[KSM 11]

Wow..

How are the power lines calculated for this type of antenna? Is it the same way as in printed patch antennas? I also wonder why there is a connection to the reflector in the central part of the element. Is this a mandatory part? I just haven't come across such antennas before.

,,,see this...

I still don't fully understand it.

How are the power lines calculated for such an antenna? Is it the same as for printed circuit boards, where only air is taken into account as a dielectric, or are different formulas used? Also, why is the element with the director bolted to the reflector at the centre of the element?

Phase and Impedance matching( Radiator Z + Feed point z)

Yes ALL ANTENNAS are the same ; any conductive material) Dielectric must be CONSIDERED (different ε (epsilon), and Tangent Loss)

A HALF WAVE radiator could be held at center point cause there is a Low impedance (high Current) point no EFFECT on general characteristics...(the WAVE is NOT MOVING at THAT specific POINT)
