Computer aided design of backfire linear array antenna in x-band

Hristov-Taylor antenna has been designed at 10 GHz without and with the dielectric strips. Experimental measurements and theoretical calculations have been made. The results have shown improved characteristics when using the dielectric strips as a single antenna only. Three proposed designs of the long backfire antenna are presented at 10 GHz with different dimensions and lengths. Hristov and three proposed antennas have been designed in linear array with uniform and non uniform amplitude distributions for even and odd numbers of the elements. The resulting characteristics have been improved for the three proposed designs when using the dielectric strips as a single and linear array antenna.
