Figure 8 Final dimensions of the CPWFA with the ground and the doubled frequency VI. CONCLUSION

In this paper, it was shown that the slot widths of the CPW in a CPWFA could be increased in order to improve the manufacturing process and reduce errors without affecting the response of the antenna. It was further shown that a ground plane could be added to the antenna, to not only shield the electronics behind the antenna, but also to improve the VSWR of the antenna and flatten out the response across the band with a small decrease in bandwidth. The only disadvantage was adding less than 1 cm to the thickness of the antenna which, even in space-borne applications, is usually insignificant. The CPWFA is a competitive alternate solution to the microstrip line-fed aperture-coupled antenna, even in applications which require no back radiation.

## Abstract Loss due to coupling between two parallel microstrip lines is investigated in this paper. It is found that the transmission characteristic of the aggressor line was impaired by coupling. Most energy would be coupled to the victim line at resonant frequencies determined by the space betw
