Impedance Matching for dual-band microstrip patch antenna

[Alfred 1]

This result okay?

[Admin 2561]

yes, it's for good..!!!

[Alfred 1]

Mean I can use this 2.3GHz result to replace 2.6GHz for LTE applications?

Thank you.

[Admin 2561]

,,,you can try to put this sma conector...

[Alfred 1]

I am using RoHs 5265757 SMA connector. Although the 2.3GHz impedance is nearly matched, nut the gain is still negative.

TT.

 

[Admin 2561]

you can post here the sizes or possibly the file * cst...???

[Admin 2561]

something like...

SMA Conector.cst

[Admin 2561]

,,,that would be simulated with SMA connector...

 

[Alfred 1]

The concern is after the SMA connector is added, the gain of the antenna become positive or not. So the gain improve to positive?

Thank you.

[Alfred 1]

Kindly help me to determine which one is E-field and which one H-field.

 

Thank you.

[Alfred 1]

Is it constant phi 0 degree for H-field and 90 degree for E-field?

 

[Admin 2561]

 

,,,depends,,,,!!!

Thanks a lot ya.

I have this antenna and I like it. I also like the fact I can put any halfwave wire for 40 and up on it and have that band. So I am not stuck to 10/20/40. No tuner needed.

 I feel good about this ... can you put some pictures?

actually I do not know what makes them,and you try it...

1111.cst

The Gain is negative .

Question : i am confused about polygon in SMA Connector?

Question 2: how we can calculate the value of "k". Please admin help me 

 

[Admin 2561]

,,,where did you find that ... ???

,,,or read this...http://www.mweda.com/cst/cst2013/mergedProjects/CST_PARTICLE_STUDIO/special_overview/special_overview_waveguideover.htm

k = 3....15

i know this one , i am finding the suitable formula to calculate the value of K for impedance matching.
