A reduced size antipodal Vivaldi antenna (AVA) design for the frequency band 6-18 GHz applications is presented in this paper. The proposed antenna shape is modified with the slot-loaded and circulated tips to achieve the high gain, good VSWR and Radiation Pattern while the total size is reduced 66% compared with the reference antennas. Simulation and implementation results of the designed antenna are verified.

—In this paper, we propose a novel interconnection technique for a flip-chip quad flat no-lead (FC QFN) package which can decrease the amount of the transmission line (TL) phase shift. The RF die inputs and outputs (I/O) are connected to the package lead fingers by a small size, 1000 µm length, microstrip line having a gap capacitor consisting of staked plates (fingers) where the space in between is filled by a ceramic material of 10.2 dielectric constant value. This technique can reduce the effect of transmission line inductance and makes the novel package interconnection behaving as a composite left right handed (CLRH) TL; hence, one can set the TL phase shift to zero degree at the desired operating frequency band (i.e., S-band) by just tuning geometrical and/or physical interconnection structure parameters.
