This article proposed a novel broadband high‐gain antenna designed by suspended cuboids and differential shorting strips on a circular ground plane. The design structure of the proposed antenna is simple and all its components such as cuboids, strips, and ground plane are fabricated by a copper sheet of thickness 0.5 mm. The proposed antenna has measured −10 dB impedance bandwidth (IBW) 45% (2.35‐3.7 GHz) with broadside gain of 10.1 ± 0.4 dBi over IBW. The use of differential strips in inner cuboid improved the cross polarization and enhanced the broadside gain. The measured antenna has low cross polarization is below 25 dB in the broadside direction over IBW. The proposed antenna has 1 dB gain‐bandwidth 53% (2.2‐3.8 GHz) in the broadside. The antenna has been fabricated and measured; the results show a good agreement with simulated results.

“…The antenna is fed from two orthogonal diameters of the cylinders from 2 coaxial probes; therefore, no external feeding networks are required. Only metal is used for fabrication of this antenna; therefore, power handling capacity of the antenna is high as compared to the dielectric and microstrip antennas [16]. The measurement results show that the antenna has −10 dB impedance 34.37% (2.65-3.75 GHz) when it is measured from port 1 and 34.21% (2.63-3.67 GHz) when it is measured from port 2.…”

In this paper, a novel low-cost, high gain dual-polarized antenna design with a suspended cylinder and a ground connected cylinder geometry is proposed. The design structure of the antenna is simple and fabricated with two cylinders, two shorting strips, and a circular ground plane. All these components are easily fabricated from a copper sheet of thickness 0.4 mm, and the antenna is fed by two coaxial probes at the orthogonal planes on the circumference of the cylinders. A prototype is designed, fabricated and measured. The measured results show that the prototype has −10 dB impedance bandwidth of 34.37% at port 1 & 34.21% at port 2. Broadside gain from port 1 is 10.2-10.4 dBi & port 2 is 10.25-10.52 dBi, which indicates that the antenna has flat gain over the impedance bandwidth, and isolation between the ports is more than 15 dB from 2.65-3.6 GHz and more than 20 dB from 2.75-3.55 GHz. The isolation of the proposed antenna is improved by shorting the suspended cylinder to the ground plane by two shorting strips. The resonance frequency and isolation peak are simultaneously tunable with varying the width of the shorting strips. The parameters of the antenna are optimized by using HFSS, and good agreement between the simulated and measured results is obtained. The proposed dual polarized antenna can be used for base station applications such as LTE (Long Term Evolution) and WiMAX (Worldwide Interoperability for Microwave Access).

“…In order to address the complexity and cost issues, we propose an extremely low‐cost dual polarized antenna of having a simple structure of suspended cylinders and fabricated using metal . In this article, a suspended cuboid is proposed and is fed of two simple coaxial probes in the orthogonal plane on the perimeter of the cuboid thus does not require any external feeding network.…”

This article presents a novel low-cost high-gain dual-polarized antenna using suspended cuboid and ground connected cuboid geometry. The design structure of the antenna is simple and it's all components are fabricated by a copper sheet of thickness 0.5 mm. The prototype is fabricated and measured and has −15 dB impedance bandwidths of 33.33%(2.5-3.5 GHz) with broadside gain of 9.2 ± 0.3 dBi and 32.25%(2.6-3.6 GHz) with broadside gain 9 ± 0.3 dBi over bandwidths when measured from port 1 and port 2, respectively. The isolation between the ports is enhanced by shorting suspended cuboid from the ground plane and measured one more than 17 dB from 2.45 to 3.7 GHz. The proposed dual polarized antenna can be used for base stations such as Wireless Local Area Network (WLAN), Long Term Evolution (LTE), and Worldwide Interoperability for Microwave Access (WiMAX) applications. The antenna is designed and simulated and there are good agreements between simulated and measured results are obtained.
