Printed Wideband Monopole Antenna with Band-notched Feature

In this article, a novel wide-band, open-ended monopole antenna is proposed and fabricated. An open-ended slot is etched on the radiating element to achieve the wide impedance bandwidth. The FR4 substrate having dielectric constant 4.4 is used to design the monopole antenna. The proposed antenna covers different band applications from 2.08 GHz to 9.68 GHz including a wider notch band (3.97 to 8.13 GHz) with a center frequency of 6.05 GHz. The notch band is achieved by etching an L-shaped slot on the partial ground plane. The proposed monopole structure achieved the maximum S
11
of -31.17 at 3.07 GHz and high gain of 3.05 dBi. The proposed wideband antenna design is appropriately suitable for L (1-2 GHz) and S (2-4 GHz) band applications.
