- Abstract
In this study, a compact ultra-wideband (UWB) two-layer printed microstrip line monopole-slot antenna with triple band-rejection characteristics is investigated. The proposed antenna consists of a planar UWB monopole-slot antenna with a size of 40 × 47 × 1.016 mm3 and a modified half-mode substrate-integrated waveguide (M-HMSIW) cavity with folded defected ground structure slot. The antenna is fabricated using two-layer printed circuit board process. To generate bandnotched characteristics, M-HMSIW cavity in the bottom layer of the antenna are utilised. By tuning the dimension of MHMSIW, triple notched bands with sharp rejection can be achieved at WiMAX band (3.3-3.69 GHz), along with a major part of the C-band (3.7-4.2 GHz), lower wireless local area network (WLAN) band (5.15-5.35 GHz), and upper WLAN band (5.725-5.825 GHz). The simulated and measured impedance matching, radiation patterns and gain results of antenna are investigated. The results of the fabricated antenna show that this antenna is a good candidate for various UWB applications.
