The design of a millimeter wave (mmW) antenna for the 5G mobile applications is presented in this paper. The designed antenna has dimensions of 10×10×0.245 mm<sup>3</sup>. This includes the copper ground plane. The resonance of the proposed mmW antenna lies within the range of 33 GHz and 43 GHz. These frequency bands are covering the 5G proposed band in terms of the signal speed, data transmission, and high spectral efficiencies. Computer simulation technology (CST) software is used to simulate the proposed 5G antenna including the characteristics of S-parameters, gain, and radiation pattern. Simulation results show that the return loss at resonant frequencies goes -22 dB, which satisfies the requirements of 5G mobile technology.

Simulation Results

In this paper, a rectangular dual band millimeter wave (MMW) microstrip antenna using U and circular slot is designed for defense applications. The antenna operates in the (57-64) GHz unlicensed frequency band. The proposed antenna is designed using RT/duroid substrate having dielectric constant 2.3, thickness 0.04mm and strip line feeding technique. The proposed antenna results are simulated and optimized using Computer Simulation Technology (CST) simulation software. The maximum return loss achieved is -15dB and -25.45 dB respectively for both U and circular slot. Simulation results show that the antenna having circular slot gave better results. The antenna simulation results such as return loss, gain and directivity are presented in this paper.

Millimeter Wave Antenna

In this paper an inset feed 60 GHz millimeter wave microstrip patch antenna is proposed for future high speed wireless communication systems. The performance of a conventional 60 GHz patch antenna compared with metamaterial-based 60 GHz antennas. The later employs three types (mushroom, cross and hexagonal) of Electromagnetic Bandgap (EBG) surfaces as a ground planes. The millimeter wave antenna employing the cross-shaped EBG give improved gain as compared to the rest of the antenna models. The 60 GHz antenna based on the mushroom type EBG present better efficiency due to the surface suppression by the ground plane. The proposed antennas can be used in future high speed wireless applications. Due to the very small size these antennas are suitable for medical implants operating in the unlicensed millimeter wave band.
