To simulate an aperture-coupled microstirp antenna in HFSS

时间:03-23 整理:3721RD 点击:
The energy is coupled to the microstrip patch througth the slot in the groud plane. A substrate and a microstirp thansmission line is below the groud.
How to establish the model and is there any good papers about that kind of antenna?

How to keep the radiation of the microstrip line from the caculation of the whole radition pattern, for I can't assign the groud plane to be infinite. The
transmission line have to be kept within the radition boundary.

there are many papers such as:
1- " A Review of Aperture Coupled Microstrip Antennas: History, Operation, Development, and Aplications"
David Pozar
May 1996

2- "Design of Wide-band Aperture-Stacked Patch Microstrip Antennas"
S. Targonski, R. Waterhouse, D. Pozar
IEEE Transactions on Antennas and Propagation, Vol. 46, No. 9, Sept 1998

3- "Analysis of an Aperture Coupled Microstrip Antenna"
P. Sullivan, D. Schaubert
IEEE Transactions on Antennas and Propagation, Vol. AP-34, No. 8, Aug. 1986

with regards,

but it is difficult to down load these papers can someone upload them

try these links:
www.ecs.umass.edu/ece/pozar/aperture.pdf
http://cegt201.bradley.edu/projects/...00/Antenna.htm
http://www.ece.rutgers.edu/~orfanidi/ewa (this is free book on the internet)

regarding IEEE papers, we are not allowed to publish them for free (as i think)

Could you be more about your problem?
Why can't you have infinite GND?

Hi mwhero,
To simulation the coulpe structure as you discribed,the best tool is De$igner or En$emble,you can try again.

What's the advantage using an aperture-coupled microstirp antenna, get more wider bandwidth ?

Thanks!

Sorry for the late reply as i have just seen it
some of the advs are
The thickness and the dielectric constants of the two substrates may be chosen independently to optimise the distinct electrical functions of radiation and circuitry. In addition, the ground plane eliminates spurious radiation from the feed from interfering with the antenna pattern or polarization purity.
Also because of the fact that it has limited BW, much work has been devoted to increasing the bandwidth of microstrip antennas
