A Novel High Gain Monopole Antenna Array for 60 GHz Millimeter-Wave Communications

Abstract

This paper presented the design and implementation of a 60 GHz single element monopole antenna as well as a two-element array made of two 60 GHz monopole antennas. The proposed antenna array was used for 5G applications with radiation characteristics that conformed to the requirements of wireless communication systems. The proposed single element was designed and optimized to work at 60 GHz with a bandwidth of 6.6 GHz (57.2–63.8 GHz) and a maximum gain of 11.6 dB. The design was optimized by double T-shaped structures that were added in the rectangular slots, as well as two external stubs in order to achieve a highly directed radiation pattern. Moreover, ring and circular slots were made in the partial ground plane at an optimized distance as a defected ground structure (DGS) to improve the impedance bandwidth in the desired band. The two-element array was fed by a feed network, thus improving both the impedance bandwidth and gain. The single element and array were fabricated, and the measured and simulated results mimicked each other in both return loss and antenna gain.

Millimeter-Wave Smart Antenna Solutions for URLLC in Industry 4.0 and Beyond

“…The beamforming antennas help to improve the coverage, SNR, and effective beam steering [ 80 ]. We broadly categorize the 60 GHz smart beamforming antennas into three types: printed circuit board (PCB)-based antennas [ 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 ], on-chip antennas [ 59 , 98 , 99 , 100 , 101 , 102 , 103 ], and low temperature co-fired ceramic (LTCC)-based antennas [ 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 ]. We discuss these antennas here in detail.…”

Simple wideband extended aperture antenna-inspired circular patch for V-band communication systems

“…Recently, various studies have been reported in literature to develop an effective antenna for the V-band communication spectrum [15][16][17][18][19][20][21][22][23][24][25][26]. In [15], a compact size button antenna for wearable applications is proposed; however, the antenna performance parameters, including bandwidth and gain, are compromised to achieve an electrically small antenna.…”

“…The antenna offers a high gain of 12 dB, having a wide operational bandwidth of 8 GHz at the cost of bigger dimensions. In [25] a conventional slotted patch antenna is designed, where DGS technique is used to attain high gain. However, use of multiple defects in patch and ground significantly increased the complexity.…”
