Abstract
En 中文
This letter presents new microfabricated point symmetric meander-line (ML) slots inserted on the ground plane to reduce mutual coupling between narrowly spaced patches in a 2 x 1 patch array antenna for a WLAN application (4.94-4.99 GHz). The distance between the patches is 2 mm (edge-to-edge space: 0.06 lambda(g)), and the ML slot unit cell has a dimension of 1.37 x 9.62 mm(2). The resonant frequency mismatch between S11 and S22 caused by the asymmetric structure of a single-ML slot has been mitigated by placing two ML slots in a complementary point symmetric fashion. The ML slots on the ground plane have been fabricated using photolithography and electrodeposition, where the smallest dimension is 160 mu m. The fabricated antenna shows a maximum isolation improvement of 34.3 dB and no resonant frequency shift between S11 and S22.
