Determination of Radius of Circular Microstrip Antenna Using Clonal Selection Algorithm
نویسندگان
چکیده
A method based on clonal selection algorithm (CSA) for computing the radius of circular microstrip antennas (MSAs) is presented. The CSA is a stochastic method which has the capability of optimizing multimodal problems. The method gives the radius as output for given values of resonant frequency (fr), height (h), dielectric constant (εr) of the circular MSAs. Results obtained for the radius of circular MSAs are in good agreement with the experimental results reported by several authors.

some analysis has been presented on a circularly polarized microstrip antenna with T slot configurations in detail. Here we will design a T-slot coupled circularly polarized microstrip antenna in the frequency 1.575 GHz. The upper patch i.e. the radiating patch would be circular. There is no closed form expression so that by using that expression the dimensions of the proposed antenna could be ...
