it is possible.
Go thr the paper,
Wideband Circularly Polarized Microstrip Patch Antenna for WLAN Applications
M.Ali,R.Dougal,G.Yang and H.S.Hwang
It is available in this forum but i dont know the exact location.

U can refer to Electronic letters u will get plenty of papers there on U-slot type antennas for ur applications
One book is also there Compact and Broadband antennas by Artech House

Need your help about this matter...
For microstrip antenna there is some techniques/methods to generate multi-frequency or enhance the bandwidth of the antenna...
I see some of those techniques are relatively the same, for instance slot could be used to generate multifreq and also widen the bandwidth...

does anyone have recomendations for papers or have papers concerning:
broadbanded patch/microstrip dipole - bw is 20%
slot coupled microstrip patch - maybe my best chance at achieving said bw?
application will require dual polarization, so some applications may not be applicable, such as slot loading the radiating element from Kin-Lu (...)

I want to design a 0.5-3 GHz Vivaldi or Horn UWB Antenna, The problem with horn is that its dimensions get very large- and vivaldi is a good option but most of the designs have good performance above 3 GHz and Designs are not available for lower frequency wideband operation,Could anyone help in achieving such a design?

i am interested in TSA (Tapered slot Antenna), generally TSA is a broadband and endfire antenna.
i do not know how to feed teflon lens to get narrow beam on your antenna.
how about use fresnel zone plate lens antenna or fresnel zone plate reflectarrays
if your application is not wideband in Ka or (...)

Patch antennas have never be known to be wideband anyway. Another thing to note is the ground-to-radiator distance.
Hope this helps,

I am simulating a wideband printed slot antenna with substrate height of 1.5 mm. I have a concrete block on top and an epoxy box at bottom attached to it. The problem i face is that if i simulate this antenna in the specified band of 100-800 MHz i get a mesh size of almost 9000 cells. The simulation is (...)

I am trying to simulate an unit cell of an UHF Arrays using HFSS with reference to:
IEEE Transactions on Antennas and Propagation, Vol 54, No.7, July 2006
-Compact Light Weight UHF Arrays Using Long slot Apertures
I've drawn out the structure of the unit cell except for the balun transformer. The requirement is a wideband 4:1 (...)

hello i m sameer. i have design a microstrip antenna i m getting very good results but its bandwidth is very low so i want to know how can i increase the bandwidth.
the basic parameters of my antenna is
relative permittivity 2.2
i have air above the ground plane and i have made some (...)

Hi thanks for the paper. I am very new in antenna design. But I am looking for an antenna with the highest gain possible maybe an array. I am not very concerned about bandwidth.
