Low cost microstrip-fed dual frequency printed dipole antenna for wireless communications

摘要

A low cost microstrip-fed dual frequency dipole antenna has been developed for personal communication network (PCN) and wireless LAN (WLAN) applications in the 2.4 and 5.2 GHz bands. The antenna radiates bi-directionally and has a double-sided structure to enable transition from a balanced planar stripline to unbalanced microstrip line. The 10 dB bandwidths achieved were 18.75 and 7.7% at 2.4 and 5.2 GHz, respectively.
