A compact fully flexible antenna with 1.22 as dielectric constant 0.016 loss tangent is designed for wearable biomedical applications. It has dimensions of 40.5 x 23 0.97 mm3. The polygon-shaped patch modified to achieve ultra-wideband frequencies using partial ground 16.5mm and a periodic vertical slot 13x2 mm2 structure in defected enhance the wide bandwidth 2.6-11.1 GHz. Using transmission l...

A wideband multiple-input multiple-output (MIMO) antenna with high isolation for fifth-generation (5G) new-radio (NR) smartphone employment operating at a range from 3.3–5 GHz is presented in the paper. The comprised of eight identical radiation units and applies defected ground structure (DGS) to offer higher between units. Each elements formed C-shaped microstrip line, two triangle-shaped str...

In this brief, a harmonic-controlled substrate-integrated defected ground structure (SIDGS) resonator with tuning capacitor is proposed for the design of tunable filter. Such exhibits characteristic. The fundamental resonant frequency can be properly tuned, while spurious resonance controlled at much higher to achieve wide stopband. To verify principle, bandpass filter (BPF) designed and fabric...
