Abstract

In this paper, a novel microstrip-fed monopole antenna is constructed and tested to cover the following operational bands: WLAN (5,150–5,350/5,725–5,825 MHz specified by IEEE 802.11a) and X-band (8–12 GHz). In this antenna, the aim is to propose a simple configuration of patch and ground plane with a step-by-step process design of conductor back plane to access dual-band specification. Frequency bands can be created, by inserting the rotated U-shaped conductor-backed plane (CBP), and for proper controlling the both bands, the U-shaped strip is embedded on. The impedance matching of the antenna is enhanced by tuning and suitable adjusting dimensions of inserted U-shaped strip. Wider impedance bandwidth is obtained by using of final structure of CBP, which provides a wide usable fractional bandwidth 21 % for 5 GHz WLAN and 52 % for X-band. The realized antenna has simple structure and compact size of \(15 \times 15\;\hbox {mm}^{2}\), moreover, can provide good omni-directional radiation patterns. Measured and simulated results of the antenna with the different forms of CBP are presented.
