The paper has been accepted by German Microwave Conference in Berlin ( http://gemic2010.fbh-berlin.de ) and will be published through IEEE Xplore.

Abstract: A design of differential Bunny-Ear Antenna (BEA) for the application of 60 GHz frequency band is presented. This antenna is fed by differential microstrip transmission line (MTL) and to be connected to the transceiver chip by bondwire. The bondwire introduces inductance and high impedance which destroys the matching, so the compensation structure for the interconnect is included in the design. In the simulation, the return loss is better than -10 dB. The radiation patterns are similar from the very low frequency of 57 GHz to high frequency of 65 GHz, with a 3-dB beamwidth of about 28 degrees in the principle planes. The measurement verifies the simulated radiation characteristics and shows that a gain of more than 9.7 dBi can be achieved by using this antenna.
