Parasitically Coupled Three Element DRA Array with Reduced Side Lobe Lavel
A three element E-plane parasitic DRA array partially inserted within a secondary substrate has been realized in this paper for broadside radiation. The proposed DRA array operates from 7.02 GHz to 7.26 GHz and gives broadside radiation pattern with a peak gain of 7.22 dBi. Four metal strips are placed in very close proximity to the DRAs which help to improve the matching as well as decrease the side lobe lavel. Three different arrangement of the array is studied here and from simulations results of S11 and radiation characteristics it is evident that embedded array with metal strips is improved the side lobe lavel almost 3.2 dB in E-plane compared to the isolated array.
