A Wideband Microstrip Patch Antenna for 60 GHz Wireless Applications

Abstract

In this paper a compact microstrip patch antenna designed for the unlicensed 60 GHz millimeter-wave band applications is presented and discussed in details. The proposed antenna consists of a rectangular radiating patch with an embedded U-shape slot inside, and excited by the coaxial probe feeding technique. A wide range of parametric studies has been performed on the patch size, feeding positions and U-slot dimensions and the antenna is optimized for the best possible results. The proposed antenna configuration achieved a wide bandwidth of 15.4 GHz (25.69 %) covering the frequency range from 52.20 to 67.70 GHz. The lowest return loss of the antenna is -41.2 dB and the maximum gain obtained is 9.52 dB at the 60 GHz resonance frequency. Considering the size, bandwidth, and gain, this microstrip antenna can be a suitable candidate for the 60 GHz wireless applications for short range high speed communications.

Size improvement of rectangular microstrip patch antenna at MM‐wave and terahertz frequencies

“…Many of them are made by connecting simpler circuits, such as T junctions, delay lines, and four-port directional couplers [1][2][3][4][5][6]. While this solution is relatively simple to design, mostly because the synthesis of a four-port coupler is well established, the footprint of the final circuit is relatively large.…”

Compact Microstrip Antenna Design for 5G Communication in Millimeter Wave at 28 GHz

“…Microstrip patch antennas (MPAs) can meet the requirements of both wireless communication systems and mobile communication systems. In addition, these antennas have advantageous features such as used on planar and non-planar surfaces, used in multi-band, and low cost (Balanis, 1998;Abirami, 2017;Saini et al, 2017;Ali et al, 2016;Alvarez et al, 2015;Alam et al, 2013;Chen et al, 2013). Although it is predicted that FR4 MPAs will not provide healthy results in bands above 6 GHz, MPAs have been observed to operate stable in millimeter wave band under appropriate measurement conditions (Kaeib, 2019;Ojaroudiparchin, 2015).…”

60 GHz Milimeter-Wave Antennas for Point-to-Point 5G Communication System

“…The 4G wireless system have already been initiated in some of the countries and is going to be in other soon. However, major problem is power consumption still persist even with the presence of 4G system [1]. Therefore The need for 5G wireless system came in order to solve the issues and the requirement of high data rate on 5 th generation wireless system is going on and expected to be initiated by 2020, and the significant growth in the customers demand for wireless communication using handsets has created the need for important development of antenna design as a basic part of any wireless system [2].…”

“…The path loss proportional to frequency square so at this high frequency band path loss is high. In 2001, Federal Communication Commission (FCC) released the unlicensed milimeterwave band around the 60GHz frequency [1], [4] This band is of immense interest due to the availability of universal unlicensed spectrum around 60GHz for short-range communication system such as indoor and underground communication and high speed wireless application [2], [3] Antennas for communication system at 60GHz shuld have a high bandwidth to achieve high data rate and should have a high gain to compensate the high path loss ath these frequencies [4]. The advantages of microstrip antenna for point-to-point operate at 60GHz is proposed which has a fast data rate and reliable gain.…”
