hello, i have a problem when i design rectangular patch antenna for gps, there are words that say
Defined reference frequency for open boundary condition (2 GHz) is larger than the lowest relevant system frequency (monitor at 1.57542 GHz).
Please check open boundary settings to ensure accurate monitor results for the lowest frequency

I'm new to HFSS and I have to simulate a microstrip gps antenna with circular polarization with frequency equal to 1575 MHz.
Using various math formulas I managed to determine the physical dimmensions of the patch ,such as the length and the width.
I decided to use an inset feed technique to obtain the 50 ohms input impedance,again determ

Actually my teacher has given me a assignment that I am a System Engineer and a customer comes to me and asks to design a gps antenna which will be installed on a bicycle. I have to develop the USER REQUIREMENT DOCUMENT (URD) & SYSTEM REQUIREMENT DOCUMENT (SRD).
SRD will contain the actual antenna (i have selected patch antenna) de

you can use this attached file for simulation.
you can also try with RFMD Ic's to implement a amplifier for the 1.5GHz patch antenna. we made a gps antenna with amplifier with SGA series Ic's. Application circuit will be available with the datasheet.

I want to test a simulation program. Therefore I’m searching for a simple patch antenna example. I need a design and the data of the antenna e.g. resonant frequency, the return loss and the gain.
Does anybody know where I can find a patch antenna example?

hi, i'm new in designing antenna, i work on project to design a patch antenna for gps, and using CST Microwave studio, i just want to know how to calculate the axial ratio. and want to know how to get radiation pattern for farfield or know the zeros and max. of radiation because after i run simulation for far field i didn't (...)
