A Tunable Inverted L Antenna (TILA) for Multiple Input Multiple Output (MIMO) mobile terminals is presented. Two ILAs with different lengths and varactor diodes are combined to enable bandwidth and resonance tunability at lower and upper bands respectively. The antenna 10dB bandwidth is tunable from 2250 MHz to 2700 MHz in the lower band and from 5000 MHz to 5800 MHz in the upper band. The realized...
A dual-band textile antenna for multiple-input–multiple-output (MIMO) applications, based on substrate-integrated waveguide (SIW) technology, is designed. The fundamental SIW cavity mode is designed to resonate at 2.4 GHz. Meanwhile, the second and third modes are modified and combined by careful placement of a via within the cavity to enable wideband coverage in the 5-GHz WLAN band. The simple antenna...
