Abstract The main aim of this paper is to obtain a large bandwidth with a low-cost and compactsized antenna. Here a rectangular patch fed with linefeed technique is designed. Wide bandwidth is obtained covering the range from 0.99–2.68 GHz. The designed line-fed patch antenna can operate in the WiMAX (2.2–3.4 GHz), WLAN (2.40–2.48 GHz) and UMTS II (2.50–2.69 GHz) frequency bands giving a maximum bandwidth of 90.18%. The simulation results were carried out by the Zeland IE3D software.

Abstract A novel high gain, wideband circle slot-loaded microstrip patch antenna is presented in this paper. The proposed design is realized using inset linefeed method. The proposed microstrip antenna has a wide bandwidth covering the range from 1.033–2.859 GHz. By using simple inset linefeed technique and by introducing circle slot, the proposed antenna on 2 GHz operating frequency showing the bandwidth 93.83% having return loss −27.57 dB, gain 7.1 dBi and good radiation efficiency of about 98% has been achieved. All results are carried out using IE3d software.

Abstract An objective of the paper is to optimize the parameters, and simulation analysis of compact wideband rectangular dielectric resonator antenna (RDRA). In this paper, a compact wideband, rectangular dielectric resonator antenna is presented using relatively low dielectric constant material and using double microstrip patch. The rectangular DRA is fed with a modified stepped microstrip feed to ensure efficient coupling between the RDRA and the feeder. The performance of the proposed antenna has been significantly improved by loading the RDRA with two narrow conducting metallic strips of suitable widths, which results in dual-resonance excitation and leads to a wider operating bandwidth (16.55â&#x20AC;&#x201C;18.66 GHz). The frequency characteristics and radiation performance of the proposed antenna are successfully optimized. Design and simulation results are in excellent agreement.
