A 8.7 Ghz Antenna Array based on New Feeding Technique of SIW

Ravi Verma

In this paper, SIW based antenna array are proposed ,a new concept of feeding technique is adopted to implement a slot antenna array .There are four radiating slots cut on patch for radiating antenna.In this all slots are cut symmetrically.A H slot cut on centre of patch. By feeding technique, we excite H slot by which four slots are excited.By this technique we improve bandwidth ranging from 8.09 Ghz to 8.9 Ghz (9.31%)and front to back ratio is approx. 17 dB and peak gain is better than 4 dB.
