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

Yes, it's possible..but with a VSWR <1.5.!!! A good antenna must to have VSWR<1,2

,,, why, never say give up...!!!

actually I do not know what makes them,and you try it... 1111.cst

,,,to better elucidate on Inset Fed Microstrip Patch Antenna....http://www.microwavetools.com/inset-fed-microstrip-patch-antenna/ ,,, and a calculator for it... inset_fed_antenna.exe

I'll try to do it the simulation cst....!!! but anyway, you have to try in the future to work with literary parts(not numbers) in the Parameter List of CST's

Alfred, you're right, I increased the size ...13,92mm at ..14.52mm(13,92+0,6) ,,,I think it must to modify the inset feedding of antenna for a good adaptation line at 50 ohm impedance

I think it's better to try this ...

Alfred, it seems that the antenna is not properly designed, look..

,,, and another improved by the addition of two lateral wings ,, but it is the most efficient solution by adding a reflector...

,,,unless if you translated feed point to the left or to the right...!!! You can try...!!!!

Universal irradiator 3G/4G MIMO 2x2 for the parabolic reflector ("dish". F=1920-2680 MHz. Works in the standards LTE2600, DC-HSPA and WIFI 2.4 GHz. Fitted with connectors, N-female. GAIN=9dBi. The feed offset parabolic antenna 2x2 MIMO UMO is designed for use with 3G/4G and WIFI (2.4 GHz) modems/routers, and other devices MIMO 2x2 of the range 1.92-2.68 GHz. Using 2x2 MIMO systems to obtain the maximum speed of data transfer provided by the operator. Advantages of the radiator UMO MIMO 2x2: The irradiator has two connectors, corresponding to orthogonal polarizations of the radiated signal. The original design of the antenna feed provides high isolation between inputs in a wide frequency band. Application a parabolic mirrors of large diameter allows you to gain a much larger antenna than other designs. The irradiator is recommended to use complete with offset short-focus mirrors (F/D=0.5-0.6). Radiating elements of the radiator securely sheltered from rain and aggressions in the plastic housing.

,,, and a rectangular antenna with circular polarization.. ,, these results ..they are, but results have improved this antenna

Follow,,, this ... ,,, and about it would result with minimal improvements...!!!!

,,, no, I think it looks like Chinese hoax ... !!! Anyway,,, I think there not exceeds that...

A change in the geometry,,, 16xthree-pole elements

A dual polarized base station antenna is provided, including a reflector having a longitudinal axis and an array of tri-pole elements disposed on the reflector. Each tri-pole element has a first side arm and a second side arm. The tri-pole element also includes a center arm which is approximately perpendicular to the first and second side arms. The tri-pole elements are oriented such that either the side arms or the center arm are parallel to the longitudinal axis of the reflector. The antenna further includes a feed network having a first signal path coupled to the first arms of the tri-pole elements and a second signal path coupled to the second anus of the tri-pole elements. In this example, the array of tri-pole elements produces a cross-polarized beam at +45 degrees and -45 degrees from the longitudinal axis. Tri-pole arrays may be used in a multiband antenna. so should look a tri-pole planar element ... ,,, and behold panel 16 three-pole elements ..

,,,try this...

the problem you say, I do not know ..

,,,ok,show me...!!!

,,look...!!!

Impedance is not good...

,,,and here is how you can get an increase in directivity with a dielectric feed on cantenna,,,

,,,port 2,4 don't in work
