Abstract In this paper, a millimeter-wave (MMW) dual-mode and dual-band switchable Gilbert up-conversion mixer in a commercial 65-nm complementary metal oxide semiconductor (CMOS) process is presented. By simply changing the bias, the proposed CMOS Gilbert up-conversion mixer can be switched between subharmonic and fundamental operation modes for MMW dual-band applications. With a low local oscillator pumping power of 3 dBm and low dc power consumption of 6 mW, the proposed CMOS Gilbert up-conversion mixer exhibits a measured conversion gain of −0.5 ± 1.5 dB from 37 to 50 GHz and 2.5 ± 1.5 dB from 17.5 to 32 GHz for the subharmonic and fundamental modes, respectively.

This paper presents a reconfigurable frequency microstrip patch textile antenna using slotted technique. The switchable frequency is achieved by implementing three PIN diode switches at the slotted ground of the antenna. It is discovered that the switching element is capable to configure the frequency at six different states of operating frequencies between 1.575 GHz until 2.45 GHz. With certain switches configuration, the antenna is proficient to produce a dual-band frequency of band 1; 1.575 GHz and 2.45 GHz and band 2; 1.588 GHz and 2.36 GHz. Besides, the antenna has successfully perform an axial ratio of less than <3 dB at the GPS operating frequency of 1.575 GHz. A shieldit super is used for the antenna radiator and felt fabric as the antenna substrate. The design and simulated result shows that the presented antenna is potential to be implemented in GPS and Wi-Fi applications.
