“…Meanwhile, the cross-polarisation level in the E-plane is higher than that in the H-plane. This is mainly because of the feed location on the y-axis and the discontinuity in the structure obtained using the shorting pins [25,28]. The probe feed possesses inherent asymmetry which generates higher order modes and consequently produces cross-polarised radiation.…”

In this paper, a comprehensive study of miniaturised broadband microstrip patch antennas for ultra-wideband applications is presented. At first, design and analysis of a compact wideband basic antenna which is composed of a folded-patch feed, a symmetric E-shaped edge, a U-shaped-slot patch and shorting pins are studied and investigated. The measured −10 dB impedance bandwidth of the proposed basic antenna is about 92% in the frequency range 3.94-10.65 GHz. To explicitly demonstrate the mechanism of the bandwidth enhancement method, the equivalent transmission line model of the basic antenna is exhibited. This model contributes the effect of different parts used in the basic antenna structure in order to predict the broadband behaviour of it. Moreover, with the use of a V-shaped slot instead of the U-shaped slot on the patch, an improved antenna with a wider bandwidth in order to cover the frequency range from 4 to 14.4 GHz is obtained. This improved design introduces comparatively a simpler structure with considerable size reduction and an enhancement of 21% in impedance bandwidth compared with the basic antenna. Experimental investigations and detailed simulations based on the parametric study are performed to describe and optimise the broadband performance of the proposed designs.

In this paper, a novel design of compact 1 × 4 patch antenna array using electromagnetic band gap (EBG) for wideband operation is introduced. Three unequal arms fed by CPW‐to‐slotline through a coupling system of 100 Ω T‐shaped slotline transitions are utilized for broadening the impedance bandwidth with multiple resonances. By adding two conventional mushroom‐type EBG (CMT‐EBG) structures on both sides of 100 Ω slotline transitions, dual wideband patch array is obtained. The proposed 1 × 4 patch array with CMT‐EBG includes two bands with the measured ranges (S11≤−10 dB) of 6.71–6.97 GHz and 8.60–11.51 GHz. Moreover, more size reduction is achieved by using an edge‐shorted mushroom‐type EBG (ESM‐EBG) for the proposed array. This design with the ESM‐EBG indicates almost 37% size reduction compared with the proposed array without EBG. In this paper, an equivalent circuit model of the proposed 1 × 4 array with EBG is also introduced to describe the process of its bandwidth enhancement. © 2016 Wiley Periodicals, Inc.

“…The upper two corners of patch have been removed by tapering the edge to eliminate stray electric fields while ground plane is partial to minimize back reflections. Furthermore, the proposed antenna provides a far greater bandwidth than recently developed antenna structures [11,12]. …”

In this paper, an edge tapered wideband rectangular patch antenna with slot and parasitic stubs has been proposed. The designed antenna shows wideband characteristics with a percentage impedance bandwidth of 112 % (below -10 dB and centered at 6.01 GHz). The proposed antenna shows excellent radiation characteristics with an average peak gain of 2.65 dB and average radiation efficiency of 83.9 % throughout the working bandwidth. The overall dimension of the antenna is 35 9 35 9 1.6 mm 3 . In order to validate the simulated results prototype has been fabricated and measured.
