“…In order to obtain a wide operational bandwidth, the modification and reduction of the ground plane was performed based on two parameters [17] [19], which are W and L respectively referring to the width and the length of the ground plane. The carried out modification was performed at the punctual contact between the feeding line and the patch antenna.…”

In this paper, a structure of a patch antenna operating at 0.5 GHz is proposed for ground-penetrating radar (GPR) applications, with an optimized performance at low frequencies. The structure was designed using FR4 substrate, with a 4.4 permittivity value, and a tangent loss equivalent to 0.021. The prototype design is backed by an optimized rectangular reflector, which has improved the antenna gain and directivity. The performance of the antenna is evaluated in terms of the return loss, gain, and the radiation pattern for two cases, with and without a reflector. When using the reflector, a good radiation pattern is obtained, a wide operational bandwidth ranging from 0.4GHz and 1.25 GHz is achieved, and an increased gain from 4.3 to 7.43dB was realized.

In this paper, a high gain antenna using Frequency Selective Surface (FSS) is proposed. The compact structure is designed from a circular Ultra-wideband (UWB) monopole. Higher order modes of UWB antenna are suppressed by decreasing the thickness of the monopole, ground plane dimensions, and increasing the gap between the ground plane and the monopole. Symmetrical portion of circular monopole is etched to form a semicircular monopole, and an off-set feed is employed. Dual band characteristics and miniaturization are achieved by etching horizontal and vertical slots and reducing ground plane dimensions. An FSS reflector is designed for gain enhancement. This miniaturized antenna offers less blockage and therefore, higher gain improvement when an FSS is used as a reflector.

“…It aims to support up to one million mobiles per square kilometre (ten times more than 4G). Once deployed, it should enable mobile telecommunications speeds of several gigabits of data per second, up to 100 times faster than the original 4G [1]. 5G will have more bandwidth than 4G.…”

In this study, we propose the design of an antenna array applicable to fifth-generation (5G) smartphones. The proposed antenna structure consists of a 2 x 2 patch antenna. The proposed antenna has a small size of 106.07 x 106.07 mm2 and is printed on an FR-4 substrate. It has good radiation efficiency in the 3.6 GHz band and a high gain of 10.6 dB. The bandwidth of the proposed antenna, which is useful for 5G applications, is approximately 0.38 GHz (3.877 - 3.295 GHz) and includes the allocated band from (3400 MHz to 3600 MHz) for 5G cellular communication systems. The objective of this work is to characterise a new antenna using the wave concept iterative procedure (WCIP), a fast numerical method, and validation is carried out by comparison using finite integration techniques (FIT). The results obtained from the two methods are in close agreement, validating the design concept. Thanks to its simple structure, compact size, good radiation performance and ease of manufacture and integration with application-specific printed circuit boards, this antenna is suitable for 5G applications. The structure was created and examined using a Keysight PNA network analyser to demonstrate its effectiveness and compliance. The prototype antenna shown is tested and the measured results are in good agreement with the WCIP method.
