The measured bandwidth of the proposed broadband Tag antenna is more than 140 MHz (820–960 MHz), which can cover the entire UHF RFID band.
— A multiple-input-multiple-output (MIMO) band-notched antenna with a compact size of only 22 × 36 mm 2 is proposed for ultra wideband (UWB) applications. The antenna consists of two square monopole-antenna elements, a T-shaped ground stub, a Compact UWB-MIMO antenna with metamaterial FSS decoupling ... To realize antenna system miniaturization and integration, silicon material is applied as substrate. The proposed antenna becomes a very compact construction with dimension of 38.2 × 26.6 × 0.4 mm 3. The proposed broadband FSS unit consists of four split rectangles and one I-shaped strip. A BROADBAND VHF-L BAND CAVITY-BACKED SLOT SPIRAL ANTENNA
