TY - JOUR AU - Tam, Hong Van AU - Quoc Danh, Luong Vinh PY - 2015/06/25 TI - Design of A Circularly Polarized E-shaped Patch Antenna with Enhanced Bandwidth for 2.4 GHz WLAN Applications JF - VNU Journal of Science: Computer Science and Communication Engineering; Vol 31 No 2 (2015) KW - N2 - This paper presents the design of a wideband circularly polarized E-shaped patch antenna for 2.4-GHz wireless local area networks (WLAN) applications. The proposed antenna is a modified form of the conventional circularly polarized E-shaped patch antenna. By incorporating additional slots into the antenna patch, the impedance bandwidth and return loss of the circularly polarized antenna are improved by about 6.5% and 12 dB, respectively. Measurements of the fabricated antennas show good agreement with simulated results. UR - //jcsce.vnu.edu.vn/index.php/jcsce/article/view/62
