Impedance Matching for dual-band microstrip patch antenna

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

Thank you.

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

TT.

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.

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

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.
