Abstract

A novel Defected Ground Structure (DGS) is proposed to miniaturize a 2×2 Modified Corporate Feed Planar Antenna Array (M-CFPA) with a modified corporate feeding network. The DGS altered the surface current distribution and shifted the resonance frequency to the lower side. After running a parametric sweep of length and width of the patch antenna element, achieved the miniaturized antenna array resonating at 2.4 GHz frequency. The proposed antenna array is designed using Rogers/RT Duroid 5,880 ( ) substrate with a thickness of 1.6 mm. The overall dimensions of the proposed Planar Array with DGS (PA-DGS) is 25.2723 % lesser than M-CFPA. The M-CFPA has a peak gain of 11.53 dB with a - 10 dB reflection coefficient bandwidth of 118 MHz. The proposed PA-DGS array exhibits a peak gain of 9.51 dB with 100 MHz -10 dB bandwidth.

HIGHLIGHTS

  • One of the major challenges faced in antenna array design is creating an efficient feed network
  • An optimum feed network is designed to miniaturize the antenna array
  • Metamaterial structures are deployed as defects in the ground plane to achieve further miniaturization
