In this paper, a Millimeter-wave (MMW) antenna has been proposed for a current and future wireless application. The proposed model has two resonances at 30.5 GHz and 52.4 GHz. The proposed model has been designed and optimized using a commercial electromagnetic simulator (CST-Studio) and focused on attaining a return loss rate that is lower than -10 dB. The proposed MMW models are built on a small thick Rogers Substrate (RT-5880) with h = 0.508 mm for the thickness, relative permittivity of εr = 2.2, and tanδ = 0.0009 for the loss tangent, while the substrate has a width w_s equal to 6 mm and a length l_s equal to 6 mm. The design process of the model came at three steps, the first step after mathematical calculations has an output of model which has feeding port of 50 ohm with a feedline base length l_b of 0.5 mm and a feedline length l_f of 3 mm, the second step was by using the tapering techniques for enhancing matched impedance after initial calculations to have a length of tapering l_t equal to 1.8 mm, then finally extracting four corner slots to the patch for creating the final proposed model. The previous design process is to assure reliability, mobility, and high efficiency for the proposed antenna. The advantages of this model are the small size, low profile, low fabrication cost, and straightforward design structure. The proposed design can be employed for a variety of Millimeter-wave applications like wireless personal area network (WPAN) and 5G application in some countries like Colombia and Mexico. The proposed model has a moderate gain of 3 dBi to 7 dBi at resonance frequencies of 30.5 GHz and 52.4 GHz, which is one of the unique characteristics of the proposed antenna. The impedance bandwidth is between 28.7 Ghz and 32.6 GHz, which is equal 3.9 GHz, and 49.7 GHz to 56.2 GHz, which is equal to 6.5 GHz respectively for the proposed model, and satisfying efficiency of about 75% and 87% as calculated by CST -Studio, and a VSWR is equal to 1, All of these positive results are more than enough to satisfy the needs of millimeter-wave wireless applications.

“…Besides circular shape, elliptical shape has also introduced as it produces a slight different modes of vibration. [5]. However the circular shapes can easily be modified in biconvex and biconcave shapes and these designs are implemented for enhancement of gain and bandwidth with an introduction of circular slots in the antenna [6], [7].…”

Widely used patch in circular shape has been cut in two semicircular shapes and joined together, arc to arc to same feed in dipolar form, produces a butterfly shape. In this paper each semicircular shapes are remodeled as bi-circular shapes for enhancement of gain so that it can be operated at a frequency of 15GHz which is applicable for 5G communication. This antenna is placed on a substrate of FR4-epoxy material. The design of the shape is based on the minimum distance of the two extreme arcs of the two parts which becomes the wavelength of the required resonant frequency. This design is compatible with all antenna requirements including S11 plot from which the resonant frequency and return loss have been determined. The software used in HFSS, by which antenna parameters like antenna gain, directivity etc. have been checked. The patch and the ground plane is of same material, copper.

This article proposes a new impedance matching method to provide an energy transformer between 50 Ω beam ports and the cavity of a Rotman lens. The model is derived from a quarter length transition line impedance transformer. The suggested matching technique is based on determining and analyzing standing wave patterns of electric field signals underneath feeding lines of the beam ports when they are excited with a designed frequency of 2.45 GHz. The proposed approach demonstrates the ability of the model to achieve an acceptable return loss compared to traditional taper line model matching methods, even though it increases the operating bandwidth frequency based on the measured results. Moreover, it solves the optimization iteration time consuming that is required to determine the tapering line length used in the conventional impedance matching techniques. The predicted results of the return loss are validated by measurements of the fabricated prototype microstrip lens printed on an FR‐4 substrate that is designed to work in the industrial, scientific, and medical (ISM) band in order to form five beams in the directions −26°, −13°, 0°, 13°, and 26°.
