Abstract—This paper proposes a compact printed ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna with a dimension of 38 × 91 mm2. The presented UWB-MIMO antenna comprises two identical patch elements with D separation distance on the same substrate. The basic single antenna structure has a novel design comprising seven circles surrounding a center circle with partial ground pla...

In this paper, a novel compact butterfly shaped printed monopole antenna for ultra-wideband (UWB) applications is presented. The proposed antenna is designed with a standard printed circuit board (PCB) process for suitable integration with other microwave components. The antenna prototype is designed then fabricated and tested experimentally. The calculated impedance bandwidth of the proposed a...

This paper presents the compact wideband loop antenna with a small size of 7.05mm’s radius covering ultra-wideband above 6 GHz, Wi-Fi, and Bluetooth bands for earbuds. The wide bandwidth proposed is obtained structure consisting capacitive loading pin inserted in middle antenna. supports multi-resonant modes. A wider can be by adjusting position pin. half-wavelength resonant frequency ba...

Antenna design in ultra-wideband (UWB) systems is a major challenge. For, in contrast to conventional systems, wherein waveform distortion by the antenna is negligible, there is potentially significant waveform distortion by UWB antennas. A further challenge to UWB system design is posed by mandated limits on power spectrum density, such as the FCC emission mask. In this paper, we join these tw...

In this paper requirements for the Ultra-wideband antenna and differences between narrow-band and ultrawideband antennas for wireless system are discussed. Also a novel printed loop antenna with introducing an L shape portion to its arm is presented. The antenna offers excellent performance for lower-band frequency of UWB system, ranging from 3.1 GHz to 5.1 GHz. The antenna exhibits a 10 dB ret...

MIMO techniques promise a significant boost in the capacity of wireless systems. In this paper, MIMO system is designed using a compact double-sided printed antenna having ultra-wideband and band-notched characteristic. The UWB antennas are designed on CST Microwave studio simulation software with return loss less than -10dB, and further using the results from CST, performance analysis of diffe...
