Hi,
I need help regarding setup of longitudinal slot array setup. I need to get the conductance of the offset slot in an array environment to get the effect of mutual coupling. I have got the isolated plots with waveguide ports and de-embedding the port at centre of the slot, however its the...
I want to design a unit cell of shunt longitudinal slot in array environment and get its resonant length curves vs offset. I have already designed a single isolated slot in HFSS and got its resonant response following Elliot and Stegens work. However I want to get the resonant response in an...
Hi,
can someone please tell me what kind of stacked antenna is this. My professor has asked me to reproduce it and I have no clue what kind of stack antenna is this. it has a very high bandwidth and high gain. how he couples i have no clue.
Regards
The meshing is good, In CST it is 10 per wavelength. for coupling I simulated the 2 horns separately with same array separation and S12 was better than 55dB.
I dont know how to plot fields between 2 antennas?
I have designed a waveguide 1:16 power divider with s11 <-30dB in required band i.e 13.75-14.5 GHz. in the same band I have designed a dual polarized square horn antenna with s11<-30db. however when I simulate the power divider and antenna array together my s11 drops from -30dB to -15dB. I cant...
hi,
yes... i have not deembeded it, i was also thinking how come s11 phase gives the phase response of the unit cell. it has the ground and the patch so every response is in it. currently i am using CST for unit cell i will shift to HFSS, just a question, how to de-embed the unit cell response...
Thanks planar metamaterials,
I have the basic understanding of TL and have designed a number of horn and patch antennas. I am just new to reflectarray antennas. Just started it as its my new task. can you refer me to some good material regarding RA antennas and unit cell specially. Any help...
HI,
can any one please help me with reflect array antenna init cell design. I have designed a unit cell with Electric and magnetic boundaries in X-plane and Y-plane. My S11 shows all powe is reflected, which is good i suppose, now how to get phase response from it and how to make reflect array...
