Design and Construction of Frequency Reconfigurable Micro-Strip UWB Antenna with Triple Controllable Notched Bands

Document Type : Original Article

Abstract

In this article a simple and compact frequency reconfigurable microstrip UWB Antenna with triple band notched is presented. The proposed antenna consists of an elliptic patch, and a micro-strip feed line. Three slots are used on the surface of patch to achieve notched bands. Each one of these slots is used in order to achieve notched band in WLAN (2.4-2.48GHz, 5.15-5.35GHz) and WiMAX (3.3-3.6GHz) bands. By changing the status of each slots Embedded on antenna by the high-frequency switches, notch bands can be controlled independently. The results of simulations and measurements show a proper impedance matching in the frequency range 2.2-11 GHz and achieving independent frequency notched bands. So, the antenna is capable of operating in one of the multiple modes which makes it an excellent candidate for UWB applications.
