Analysis of the Slot on a Dual-Band Antenna

Abstract

In this paper, we propose a low-profile planar dual band WLAN antenna application on wireless audio. In order to offset with the frequency-shift effect caused by plastic material, the frequency was designed higher than the default application frequency to facilitate/enable the application with added plastic material. The Default application frequency 2.4 GHz & 5 GHz for BT and WIFI, adjust the impedance matching by adjusting the coupling using slot of the two structures on the dipole antenna, so that the energy can be transmitted most effectively.
