A low-profile ( 0.035λ0 ) frequency-reconfigurable filtering patch antenna with a single-layered substrate is proposed in this communication. Parasitic strips and stubs are utilized to realize the ...

This paper proposes a circuit topology which reduces the chip size of single-pole–double-throw (SPDT) quarter-wavelength bandpass filter-integrated switches (FIS). A 40-GHz mHEMT MMIC SPDT switch has ...
