In this paper, a quasi-self-complementary antenna (QSCA) for multifunctional (i.e., wideband and dual-band wireless local area network (WLAN)) applications is presented. The proposed antenna consists of a pie-shaped radiating patch fed by a 50-Ω microstrip line and its complementary metal structure connected to the ground plane. With properly adjusting the angle (θ) of the pie-shaped notch and the...
Design of a coplanar waveguide (CPW)-fed rhombus slot antenna for dual-band operation is proposed. With appropriate rhombic ring feeding structure and rectangular bulge components for impedance matching, the proposed antenna can provide two separate impedance bandwidths of 607 MHz (about 24.7% centered at 2.45 GHz) and 1451 MHz (about 26.3% centered at 5.5 GHz), which satisfies the WLAN operation...
