A 60-GHz low-profile, wide-band, and high-gain E-shaped patch array with parasitic patches

This paper presents a 60-GHz low-profile, wide-band, and high-gain E-shaped patch array with parasitic patches for 60-GHz band. To enhance the bandwidth with low-profile single layer structure, E-shaped patch antenna is applied to form a two resonance frequencies. To increase the antenna gain, parasitic patches are adopted to E-shaped patch array for additional radiation of the antenna array. The height of the antenna is 250um, and the realized gain, 3-dB bandwidth, and impedance bandwidth is 20.2dBi, 20.2%, and 23.7%, respectively.
