Wideband 94 GHz On-chip Dipole Antennas for Imaging applications

A three way active phase shifter chip was integrated to RF circuit on the RO3003 board using wire bonding technique. The insertion loss that can be obtained from

As shown in figure 10, after connecting the designed antenna to the Butler Matrix, the return loss of the antenna system is below -18 dB in the desired band; and the port

The proper isolation between the ports causes the envelope correlation coefficient below -20 dB which makes antenna to be employed as a compact antenna in

Antenna radiation pattern is measured between ±50° using a manually turning setup with a 25 dBi gain horn

In this paper, we design and optimize all parameters of dipole antenna and its feeding LC balun circuit, while by etching silicon under the dipole antenna and placing the

Etched substrate and the metal lines for the dipole To decrease the total chip area, the on-chip strip dipole antenna is also integrated with the lumped LC balun as shown in Fig..

Note that wider bandwidths can easily be obtained by using a thicker substrate. In Figure 8, the simulated and measured return losses of the antenna are shown for the band of 5.6

2x2 UHF RFID antenna array system at 867 MHz, which consists of phase shifter, power dividers and microstrip patch antenna is designed, implemented and measured. The main beam of
