Abstract-In this paper, we present an innovative method of crosspolarisation suppression by forming the antennas in a so called Clover Array (CA). Such structure enables usage of polarisation diversity even for UWB systems. The simplified theoretical model of operation is presented as well as exemplary results of crosspolarisation patterns. The theory was verified for CA of planar Volcano-Smoke antennas. For fabricated array the cross-polarisation in main beam is below −14 dBi in the whole FCC-UWB frequency range (3.1 GHz-10.6 GHz).

Abstract-In this paper, the self-complementary principle has been applied to develop the traditional planar monopole antenna into a dipole antenna whose frequency range exceeds UWB requirements. The proposed design has compact, planar, and simple shape arranged in self-complementary manner connected to the (SMA) connector via rectangular microstrip line. The self-complementary structure offers better reduction of the imaginary part of antenna impedance, which allows matching on a wider band of frequencies. The proposed antenna showed −10 dB return loss bandwidth extending from 1.86 GHz up to 17.7 GHz. Moreover, this antenna has a simple shape as compared with complicated and irregular shapes with curves, slots or parasitic elements. The proposed design is validated by experimental measurements. The phase of the return loss is investigated for more insight into antenna matching.

“…The wider slot gives more bandwidth, and the optimum feed structure gives good impedance matching [11]. The CPW feed line with various possible patch shapes available in the literature such as 'T', cross, forklike, volcano and square are used to give wide bandwidth [12][13][14][15]. The proposed antenna in this paper designed with a compact rectangular slot and a cross like structure at the anterior portion of the feed.…”

Abstract-Design and analysis of a compact coplanar waveguide (CPW) fed Ultra Wideband (UWB) slot antenna is presented in this paper. The antenna consists of a rectangular slot with cross like structure at the anterior portion of the feed which acts as tuning stub. The CPW feed is designed for 50 Ω impedance. The physical dimension of the proposed antenna is 19 mm (length) × 20 mm (width) × 1.6 mm (thickness), and the electrical size is 0.3λ l (length) × 0.32λ l (width) (f l = 4.8 GHz). The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. An extensive analysis of the proposed antenna in the frequency and time domains is presented. The antenna was fabricated with FR4 substrate and characterized by measuring return loss, radiation pattern (5.5 GHz) and gain. The measured results are appreciably in good agreement with the simulated ones. A better impedance bandwidth is obtained from 4.8 GHz to 12.8 GHz that constitutes a fractional bandwidth of 90% with return loss less than or equal to −10 dB (VSWR ≤ 2). Time domain analysis of the antenna is also performed, which witnessed the linear phase and less distortion. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication that may be built for any wireless UWB device applications.
