Summary:
This paper presents a dipole-loaded notch antenna designed for the operation of the dual-band WLAN application. The antenna structure starts with a quarter-wavelength slit cut on a ground plane with suitable addition of a planar wire dipole connected to the open ends of the notch. The monopole notch is designed to radiate at the low frequency band, 2.4 GHz for IEEE 802.11b/g, while the planar wire dipole is responsible for the other band, 5.2/5.8 GHz for IEEE 802.11a. It is found that the wire dipole has the side effect of reducing the slit length due to its capacitive loading effect at the low frequency band. The parametric study is performed to demonstrate the characteristics of the proposed antenna, from which the guidelines for the design of the proposed antenna are provided.
