Admittance Matching of 60 GHz Rectangular Dielectric Resonator Antennas for Integrated Impulse Radio

Summary, in English

Methods to achieve admittance matching of rectangular dielectric resonator antennas intended for 60~GHz impulse radio are reported. The motivation is to find a suitable antenna that may be integrated in the V-band gated tunnel diode wavelet generator, replacing its tank circuit and forming a low complexity transmitter. Probed one- and two-port scattering parameter measurements have been performed to characterise the fabricated antennas. Changing the feed structure from a tapered dipole to an offset fed and tapered slot, a change from capacitive to inductive characteristics is observed, and the matching to the gated tunnel diode is improved. Deembedded admittance resonance frequencies of fabricated antennas were found at 53.6 and 52.2~GHz for dipole and slot fed antennas, respectively. Characterising the transmission link between dipole fed antennas, a maximum antenna gain of 10.5~dBi and a 3~dB power bandwidth of 1.5~GHz were found at 53.3~GHz.
