Bond-wire interconnected 60-GHz low-profile series fed E-shaped patch array with parasitic patches

In this paper, bond-wire interconnected 60-GHz low-profile 4-element series fed E-shaped patch antenna array with parasitic patches is presented for practical use. The proposed antenna shows 14.5dBi peak realized gain, 14GHz 3-dB gain bandwidth, and 10GHz impedance bandwidth. The proposed antenna with bond-wire interconnect can provide 14.2dBi peak realized gain, 14GHz 3-dB gain bandwidth, and 14GHz impedance bandwidth, and this band fully covers the 60–GHz ISM band. Although the proposed antenna interconnected to CMOS chip with bond-wire, the radiation pattern was not distorted at all.
