  • Queueing analysis of ultra-wideband medium access control protocol
           with finite buffer
    • Authors: Mohamed Ali Ahmed, Hassan Al-Mahdi
      Pages: 1 - 15
      Abstract: Ultra-wideband (UWB) communication has recently emerged as a technology that offers high data rate services for future wireless personal area networks. Due to its high bandwidth, it is substantial effort to design medium access control (MAC) protocols that perfectly utilise the available shared bandwidth offered by UWB technology. This paper introduces an extensive 4-dimensional finite Markov chain queueing model to investigate the performance of a multi-band protocol that was proposed in literature in terms of system occupancy, waiting time, throughput, packet loss and blocking probabilities. Our motivation is to precisely estimate packets collision probability due to randomly selection of receivers or bands. Besides introducing the finite buffer, our queuing model reflects the system behaviour in-depth. Next, we validate the obtained analytic results using discrete-event simulation. Finally, we introduce an outline of a proposal to eliminate the randomness of selecting receivers and bands.

  • Compact UWB filter with narrow notched band based on grounded circular
           patch resonator
    • Authors: Mona Yazdani Shavakand, Javad Ahmadi-Shokouh
      Pages: 16 - 21
      Abstract: In this paper, a compact ultra-wideband (UWB) band-pass filter (BPF) with a single narrow notched band is proposed. This filter is designed using a novel multiple-mode resonator (MMR) based on a grounded circular patch resonator (GCPR). The proposed MMR generates three main resonances and two transmission zeros (TZs). A semi-lozenge slot (SLS) is proposed to control resonant frequencies and obtain UWB operation. The 3dB notched band is achieved from 5.65-5.8 GHz by connecting an arrowhead stub inside the filter. The UWB filter has been simulated, fabricated and measured. The dimension of the designed filter is about 0.31 × 0.31 λg × λg.

  • High gain dual-polarised pentagonal microstrip antenna for wireless
           communications
    • Authors: Raghunath Subhanrao Bhadade, Shrinivas Padmakar Mahajan
      Pages: 22 - 31
      Abstract: In this paper we propose a dual polarised pentagonal microstrip antenna for massive MIMO-base station to operate at 2.4 GHz WLAN band (IEEE 802.11 b/g/n/ax). The various researchers have used antenna array with different feeds for the massive MIMO BS to obtain the desired gain with required impedance bandwidth. However, this proposed work contradicts with existing method by using a single novel radiating element with suspended substrate to achieve the desired gain and required impedance bandwidth. The circular polarisation is achieved by using two coaxial-probe feeds. The main focus of research is on the selection of proper shape of the radiating element for Massive MIMO BS. The proposed antenna is successfully simulated using HFSS 13.0, fabricated on a FR-4 substrate and measured. The proposed antenna exhibits a much higher gain of 6.17 dB, improved impedance bandwidth of 171.9 MHz (return loss, S11=−10 dB), the axial ratio (AR) is 1.78 dB (< 3 dB), the patch area of 1,775 mm<SUP align="right">2</SUP>, and also yields return loss better than −15 dB around the centre frequency of 2.45 GHz. The measured characteristics of the antenna are in good agreement with the simulated results.

  • Design and analysis of multi-band circle shape MIMO antenna using defected
           ground structure to reduce mutual coupling
    • Authors: K. Vasu Babu, B. Anuradha
      Pages: 32 - 40
      Abstract: In the present paper, a multi-band circle shape MIMO radiator with and without dumbbell-shaped parasitic element for all wireless applications is proposed. The proposed antenna comprises MIMO circular shape radiating patch with U-shaped inverted slot and pair of rectangular slits. By adjusting U-shaped inverted slot, a pair of rectangular slits and neutralisation line we obtain distinct resonance frequencies centred at 3.5, 5.3, 7.0 and 8.8 GHz. The VSWR results are centred on ≤ 2 at these resonant frequencies. The far field values obtained at a wide operational bandwidth, the simulated results represent that the multi-band antenna can cover sufficient bandwidth for entire frequency bands. The multi-band antenna also shows a radiation pattern of an omni directional with an acceptable average peak gains at the resonant frequencies are 5.238 dBi, 7.044 dBi, 6.763 dBi and 7.852 dBi of LTE/WLAN bands, WiMAX band, and ITU and satellite band system applications.

    • Authors: K. Vasu Babu, B. Anuradha
      Pages: 41 - 48
      Abstract: Multi-band orthogonal frequency division multiplexing ultra-wideband (MB OFDM UWB) communication system has been a leading proposal in the IEEE 802.15.3a standard and has been adopted in the ECMA standard for wireless personal area networks. In this paper, the performance of the MB-OFDM UWB communication system in the Saleh-Valenzuela multi-path UWB channel model using different antenna scheme configurations has been analytically evaluated. The analytical evaluation has been investigated for the three antenna scheme configurations which are the single input multiple output (SIMO), the multiple input single output (MISO), and the multiple input multiple output (MIMO). The issue of existence of high power inband interference signal such as the IEEE802.11n has been also analytically evaluated. A practical link budget analysis is considered. It was shown that the performance of the desired MB-OFDM UWB SIMO/MISO/MIMO communication system can severely deteriorated due to presence of such high power inband interference signal. The obtained analytical results are validated with the aid of extensive simulation results.
