Abstract
The paper proposes a simple four-element microstrip patch array antenna fed with corporate-series technique. The paper compares the proposed design with four-element antennas fed with only series-fed and corporate-fed microstrip antennas. All three antenna designs use rectangular microstrip patch elements with two insets and slots on both sides of the patch. The patch elements are accompanied by Yagi elements: three director elements and two reflector elements. Through comparison of simulation results, the paper shows that four-element array antenna with combined corporate-series feeding technique performs better compared to antennas with only either series or corporate feeding network. The proposed corporate-series fed antenna achieves better performance with wide frequency bandwidth of 25.04–30.87 GHz and gain of 9.5 dB. The antenna has an end-fire radiation pattern. Overall performance shows that the proposed corporate-series-fed microstrip patch antenna with Yagi elements is suitable for next generation 5G communication.

Progress in the field of technology has become inevitable with the beginning of the industrial revolution
Owing to the growth in mobile technology across the world and user demands for wireless devices and applications such as Internet of things (IoTs) that require higher bandwidths has led to a global bandwidth shortage for current wireless cellular networks. e 5th generation (5G) communication system is the answer to these new demands; this technology offers a larger spectrum and coverage, energy efficiency, and high data rate (10–50 Gbps), and the device density that it supports is higher than that supported by current 4th generation (4G) systems. e 5G system shall exploit millimeter-wave bands [1] and further improve the communication experience. e ird Generation Partnership Project (3GPP) has allocated the spectrum for 5G in two different frequency ranges
A simple array antenna fed with the series feed technique with Yagi elements was designed and simulated in HFSS. e array antenna was simulated with different stub lengths. e stub length in which the bandwidth performance of the antenna was wide was chosen
Summary
Progress in the field of technology has become inevitable with the beginning of the industrial revolution. Owing to the growth in mobile technology across the world and user demands for wireless devices and applications such as Internet of things (IoTs) that require higher bandwidths has led to a global bandwidth shortage for current wireless cellular networks. E 5G communication system is the answer to these new demands; this technology offers a larger spectrum and coverage, energy efficiency, and high data rate (10–50 Gbps), and the device density that it supports is higher than that supported by current 4G systems. Patch antennas support various feed techniques and can be developed into arrays to improve the gain and achieve the desired pattern requirements. Owing to these reasons, patch antennas have proven to be a strong candidate for millimeter-wave applications.
