In this paper, a reconfigurable slot antenna capable of tuning a full octave in frequency from 2 GHz to 4 GHz is presented. The design is based on changing the capacitive loading of a slot antenna by physically displacing a metal plate connected to a

A substrate integrated waveguide band-reconfigurable filter with four configurations: 1) dual band; 2) low band; 3) high band; and 4) no-band, is presented. Liquid metal is chosen to enable switching between the different configurations by filling or

The design of a dual-polarization antenna with high isolation between ports has always been a challenge in the antenna community. To overcome this issue, a pair of printed collocated bent dipoles with a unique excitation method, is introduced in this
