Abstract
—The design of multiband antennas is useful for providing multiple resonance frequencies required for multiple application scenarios. However, there is a scarcity of compact-sized antennas in the 70-110 GHz band. In this regard, this paper proposes two multiband millimeter wave antennas in the W and D bands. A small-sized antenna operating at five different frequencies (penta band) with an overall dimension of 4.8 × 5.4 mm2 and resonances at 35.84 GHz, 46.07 GHz, 56.74 GHz, 81.6 GHz, and 110.09 GHz is proposed first. The second one is an array antenna from the first antenna with a size of 11.1 by 6.4 mm2 and resonances at 28.03 GHz, 36.5 GHz, 53.11 GHz, 65.98 GHz, 77.64 GHz, 89.3 GHz, 100.52 GHz, 111.74 GHz, and 122.19 GHz. Computer Simulation Technology (CST) Microwave Studio tool is used for antenna design purposes. At the two larger frequencies of 81.6 GHz and 110.09 GHz of the first antenna, (the BW, the directivity, the gain, and radiation efficiency) are (3.3 GHz, 6.486 dBi, 6.22 dB, and 94.06%), and (10.01 GHz, 8.797 dBi, 8.506 dB, and 93.52%), respectively. At 77.64 GHz, and 111.74 GHz of the array antenna, (the BW, the directivity, the gain, and radiation efficiency) are (3.73 GHz, 12.35 dBi, 10.68 dB, and 67.9%), (4.4 GHz, 15.31 dBi, 14.07 dB, and 75.23%), respectively. The advantage of the proposed antennas over the currently available 80 GHz and 110 GHz antennas is that they are compact in size while maintaining high bandwidth and gain. Hence, the proposed antennas have potential applications in satellite communications, the Internet of things, compact biomedical devices, and interferometry radars.
