Design of microstrip wideband filtering antenna using network synthesis theory of wideband chebyshev filter
M. Ohira, K. Sato, and Z. Ma
Proc. of 2018 Thailand-Japan MicroWave (TJMW2018)      Jun 2018
In this paper, a new Nth-order wideband microstrip filtering antenna (filtenna) structure is proposed, which can be designed with a network synthesis theory of wideband Chebyshev bandpass filters. The filtenna simply consists of (N-1) shorted-end ...
A novel microstrip symmetric diagonal cross-coupling quadruplet bandpass filter using even/odd-mode stepped impedance resonators
R. Mikase, M. Ohira, Z. Ma, and X. Wang
Digest of 2018 IEEE MTT-S International Microwave Symposium   712-715   Jun 2018   [Refereed]
In this paper, a novel symmetric quadruplet coupling scheme for two symmetric/asymmetric transmission zeros (TZs) is introduced, and its new symmetric microstrip filter is proposed for a bandpass filter (BPF) design having high skirt selectivity a...
A new microstrip bandstop filter for fully canonical Cul-de-Sac coupling configuration
M. Ohira, M. Kanomata, Z. Ma, and X. Wang
Digest of 2018 IEEE MTT-S International Microwave Symposium   708-711   Jun 2018   [Refereed]
A new microstrip fully canonical Nth-order Cul-de-Sac coupling bandstop filter (BSF) is proposed in this paper. A Cul-de-Sac coupling matrix based BSF design allows to provide an equiripple stopband response with reflection zeros at passbands, kee...
B. Ren, H. Liu, Z. Ma, M. Ohira, P. Wen, X. Wang, X. Guan
IEEE Access   (6) 21850-21858   Apr 2018   [Refereed]
In this paper, a new quadruple-mode stepped-impedance square ring loaded resonator (SI-SRLR) is proposed, and a high-performance dual-band differential bandpass filter (BPF) is developed. Resonant characteristics of the SI-SRLR are investigated by...
