In April 2005, he joined the Department of Electronics, Graduate School of Information Science and Electrical Engineering, Kyushu University where he is currently an assistant professor. His current research interests include the employment of passive components such as CPW in RF CMOS system LSI, EMC and signal integrity issues of LSI, and low-noise and high linear RF front-end architectures. He is a member of the IEEE. Dr. Pokharel was a recipient of the Monbu-Kagakusho Scholarship of the Japanese Government (1997-2003) and an excellent COE research presentation award from the University of Tokyo in 2003.

N2 - We designed an electrically small antenna (ESA) with the impedance matching circuit on the thin patterned circuit board. Matching circuit is realized by using interdigital gap and transmission line which is composed of coplanar waveguide (CPW). By using our new impedance matching circuit, we can reduce the total antenna size much smaller than one-wavelength. Moreover, we design some ESAs with impedance matching circuit, which have various gains, and discuss about the relations between peak realized gains and S-parameters. Also, we fabricated and measured the ESAs, and compared experimental results of S-parameters and simulated gains.
