“…Capacitance C is directly proportional to the area that represents the mapping of the patch on the feed line (a) and inversely proportional to the patch substrate thickness (h), such that: where ε 0 and ε r are the permittivity of free space and the relative permittivity of the patch substrate, respectively. The capacitance (C f ) can be calculated as [40]:…”

Abstract-Wideband arrays have recently received considerable attention in 5G applications to cover larger frequency bands. This paper presents a novel design of a high gain and wideband antenna subarray from 23 GHz to 32 GHz, which covers the frequency bands proposed by the Federal Communications Commission (FCC) for 5G communications. The proposed subarray consists of four radiating elements with wideband and high gain characteristics. These elements are composed of two stacked patches, which are fed using the proximity coupling technique. A unit-cell element prototype is first fabricated and tested to validate the gain and bandwidth performances. A 1 × 4 subarray prototype is then fabricated and tested, while maintaining an element spacing less than half-wavelength at the center frequency, to avoid grating lobes and to keep the small size of the antenna subarray. The measurement results of the prototypes, i.e., unit cell element and subarray prototypes, show good agreements with the simulations. The subarray measurements demonstrate a high gain of 10-12 dBi, an impedance bandwidth of 33.4%, and a 1-dB gain bandwidth of 10.5%. The proposed antenna subarray is a good candidate for wideband and high gain antenna arrays suitable for 5G mmW applications.

“…An impedance bandwidth of about 30% was typically achieved if a proper U-slot was cut in the patch [6]. The BW of CMSA (Circular Micro Strip Patch) is increased by cutting the slot at an appropriate position inside the patch and these slot cut CMSAs are optimized on substrates with thickness more than 0.09λo, the proximity feeding as well as L-probe feeding has been used [4,9,16]. For this basis, various efficient methods [5][6][7][8] were proposed to solve this problem, including the use of probe compensation [5], the U-slot [6], the L-probe feed [7], and use of the T-probe feed [8].…”

“…The bandwidth restraint can be surmounted by differing from classic design. Introducing parasitic elements to the patch or cutting slots to diverge the surface current distribution, including the use of high-dielectric-constant substrate and cover layers [9], a short circuit [10], and a short pin [11], can get better the bandwidth further. Proximity and Aperture coupled feeds are non contacting schemes, in which electromagnetic field coupling is done to transport power among the micro strip line and the radiating patch.…”

Many applications of micro strip antenna are constricted by their innate narrow bandwidth. In this paper a survey on the different feeding technique, which are micro strip line feed, coaxial plane feed, proximity coupled feed and aperture couple feed, for wireless micro strip antenna is done. Micro strip line and coaxial probe feeds are contacting scheme, in which RF power directly to the radiating patch. Proximity and Aperture coupled feeds are non contacting schemes, in which electromagnetic field coupling is done to transfer power between the micro strip line and the radiating patch. In this paper, a new approach is projected to design inset feed micro strip antenna with slots in it to develop the antenna bandwidth. The input impedance matching method for antenna is predominantly vital for a feed technique. The design of slotted micro strip antenna on a substrate of thickness 11mm that give wideband features is based on embedding an inset look analogous proximity L shape feed to improve bandwidth. The Method of Moments (MOM) base IE3D software with the method of moment (MOM) ensemble has been used to in the circular patch performance comparison for the improvement of the impedance bandwidth and the power radiated with slots on the same physical dimensions.

“…Circular micro strip patch configurations are the one of most common because of their simplicity of analysis, fabrication, and their smart radiation characteristics, especially the low cross-polarization radiation which makes it good for circular polarisation (CP). The BW of CMSA is increased by cutting the slot at an appropriate position inside the patch and these slot cut CMSAs are optimized on substrates with thickness more than 0.09λo, the proximity feeding as well as L-probe feeding has been used [4,9,16]. In proximity feeding, a coupling strip is placed below the radiating patch and through the electromagnetic coupling linking patch and strip, a broadband response is realized.…”

“…Perturbation can be made by shorting an annular slot [11], rectangular bent slot [12]. Circularly polarization can also be achieved by designing a corner truncated square patch, a circular patch with cross slot, or micro strip fed proximity couple ring design [13][14], a single probe fed stacked micro strip antenna [15] and L-probe fed with cross slots [16]. A single fed design normally provides narrow bandwidth.…”
