“…The designs reported in [15] and [16] offer larger gain, but their structures are bulky and occupy larger volume as they use reflect array or space fed techniques for gain enhancement. Due to the use of conical horn, the gain realized in [18] is more, but the proposed configuration is planar and offers equivalent gain and BW values. Thus as against the reported techniques of gain and BW enhancement, the present paper proposes simpler planar gap-coupled configurations of sectoral MSAs with arc shape MSAs which offer equivalent BW and gain results against the reported designs.…”

“…Using array of gap-coupled rectangular MSA and vertex truncated triangular MSA, wideband and high gain design offering 12 dBi of gain is reported [17]. The design of a coaxially fed circular patch integrated with conical horn antenna is reported which gives gain of 12 dBi [18]. The design of a printed Yagi-Uda antenna is reported which yields peak gain of above 8 dBi [19].…”

Wide bandwidth and high gain designs of sectoral microstrip antennas gap-coupled with parasitic arc shape patches are proposed. In 1800 MHz frequency band, optimum response with bandwidth of more than 50% and peak gain of 10 dBi is obtained for 30 • sectoral angle employing two gap-coupled arc shape patches. Further gap-coupled variations of slot cut single arc shape patch with 60 • sectoral patch is presented. This design yields bandwidth of above 930 MHz (∼ 53%) with peak gain of more than 10 dBi. The comparison for the proposed gap-coupled sectoral variations with reported antennas is presented. Proposed gap-coupled sectoral configurations are single layer and thus simple in design and yet offers bandwidth and gain of larger than 50% and 10 dBi, respectively.

The cloud radio access network (C-RAN) is one of the most efficient, low-cost, and energy-efficient radio access techniques proposed as a potential candidate for the implementation of next-generation (NGN) mobile base stations (BSs). A high-performance C-RAN requires an exceptional broadband radio frequency (RF) front end that cannot be guaranteed without remarkable antenna elements. In response, we present state-of-theart antenna elements that are potential candidates for the implementation of the C-RAN's RF front end. We present an overview of C-RAN technology and different types of planar antennas operating at the future proposed fifth-generation (5G) bands that may include the following: (i) ultra-wide band (UWB) (3-12 GHz), (ii) 28/38 GHz, and (iii) 60-GHz radio. Further, we propose different planar antennas suitable for the implementation of C-RAN systems. We design, simulate, and optimize the proposed antennas according to the desired specifications covering the required frequency bands. The key design parameters are calculated, analyzed, and discussed. In our research work, the proposed antennas are lightweight, low-cost, and easy to integrate with other microwave and millimeter-wave (MMW) circuits. We also consider different implementation strategies that can be helpful in the execution of large-scale multiple-input multiple-output (MIMO) networks.

“…Metallic patterns are placed on both sides of a dielectric slab which act as a Fabry-Perot cavity along with the ground of a patch antenna, which is used to absorb the incident waves on the top side. To enhance the gain of microstrip antennas (MSAs), conical horn hybrid technology was also developed which is the most effective for short-range communication with a gain enhancement of around 6 dBi [10]. A high gain reconfigurable polarized magneto-electric dipole antenna where a magnetic dipole is formed using aperture between the patches and horizontal patches with strip results in a planar electric dipole [11].…”

In this paper, a high gain wideband circularly polarized (CP) microstrip antenna is presented for broadband operation. The proposed structure comprised of a partially grounded printed monopole antenna loaded with a split ring resonator and a metallic reflector. By using the metallic reflector surface underneath the patch radiator results in the reflected waves in the same phase with main lobe radiation, thereby improving the gain and it also acts like a secondary radiator to generate wideband CP behavior in the proposed design. A gain enhancement of 4.3 dBi is achieved in the operating frequency band as compared with the design without a metallic reflector. The maximum gain achieved in the presented method is 8.6 dBic over the entire operating range. The proposed design shows a wideband behavior ranging from 4.30 to 9.10 GHz with the 10-dB impedance bandwidth of 71.64%. In addition, the proposed design yielded a broadside right hand CP radiation with a 3-dB axial ratio bandwidth of 33.88% from 4.98 to 7.01 GHz. The proposed antenna is fabricated and experimental results on reflection coefficient, gain, axial ratio, and radiation patterns concede well with simulation results.
