Abstract: Role of feeding is very important for the efficient operation of an antenna. Changes in the feeding structures improve (i) bandwidth (BW), (ii) return loss and (iii) impedance matching (IM). Common coaxial feeding produces low return loss and good IM, but it yields narrow BW. Proximity feeding increases BW and eliminates spurious radiation at the cost of high losses. Dynamic feeding attains low losses, good IM and narrow BW along with frequency reconfiguration (FR). This paper aims to produce broad BW and FR antenna with the help of Dynamic Enhanced Proximity Coupling (DEPC) technique. In this, a multiple substrate layer antenna with a patch in one layer and feed in another layer along with ascension of feed position produces a low loss, broad BW and FR antenna. The DEPC design, which is tested on rectangular patch and fractal structures, achieves improved current distribution and overall BW compared to other techniques.
