  ABSTRACT: Dual-polarised microstrip flat panel antennas suited for radio-over-fibre (RoF) micro-cellular distribution systems are presented. The antenna units are intended to be low-cost and compact, provide reasonable gain, and serve the 4G-long term evolution (LTE) wireless band in a Manhattan scenario. A design study has been carried out to assess the effects of mutual coupling between the required sectors for the scenario. Return loss, isolation on dual ports, and radiation patterns are shown. Improved matching lines for optimum optical fibre link gains using cost/performance units are also introduced.

  ABSTRACT: A small volume multiband planar inverted-F antenna (PIFA) with an electrically unconnected multi-strip ground plane is presented. The proposed antenna is low cost and easily fabricated, operates over a wide range of mobile communication standards with 3.57:1 and 2.32:1 VSWR at 0.89-2.48 and 3.1-10.6-GHz, respectively.

• Conference Proceeding: Miniature narrow band PIFA antenna for high performance wireless systems

  I.J.G. Zuazola, J.C. Batchelor, J.M.H. Elmirghani
  [show abstract] [hide abstract]
  ABSTRACT: This paper introduces a miniature narrow band antenna for high performance systems using the WiMAX unlicensed band (5.470-5.725 GHz). This performance is achieved as a result of a low VSWR circle and ldquoQrdquo quality factor. The antenna return loss (RL), VSWR circle and ldquoQrdquo quality factor contour will be shown. Owing to its compact design this antenna is suitable for equipment integration as small as mobile handsets.

• Conference Proceeding: WiMAX antennas for Intelligent Transport System communications

  ABSTRACT: Antennas suitable for Intelligent Transport Systems (ITS) are overseen. The antennas serve a narrow-band high performance unlicensed 5.470-5.725 GHz Worldwide Interoperability for Microwave Access (WiMAX) deployed over a full-duplex bi-directional optical link. The system is composed of 3-RFports aimed to support Adaptive Antenna System (AAS), Multiple-Input Multiple-Output (MIMO) and Sectorization, for communications of about 70 ~ 100 Mbps over micro-cells along highways to moving vehicles incorporating a Ultra Wide Band (UWB) network of 480 Mbps. A design study has been carried out to assess the most cost-effective while efficient antenna units. The effects among antennas seen as interferers are also considered.

• Conference Proceeding: Miniaturised Multiband PIFA Antenna using a Frequency Selective Surface (FSS) Ground Plane

  I.J.G. Zuazola, J.C. Batchelor, R.J. Langley
  [show abstract] [hide abstract]
  ABSTRACT: Given the constrained geometry of modern mobile equipment, the design of small volume antennas such as planar inverted-F Antennas (PIFAs) is of great interest. In devices such as laptops, PDAs, and phones, antennas must be low profile and compact by Huynh, M.-C and Stutzman (2004). Here a novel low cost, easily fabricated, miniaturized multiband PIFA antenna with a frequency selective surface (FSS) as a bottom layer is presented. The miniature PIFA is designed for GSM 900, GSM1800, DECT, DCS, UMTS, Bluetooth (WLAN) and HiperLAN 1&2.
