AbstractThis paper presents a novel integrated antenna system for cognitive radio (CR) applications. The design consists of a compact 4- element reconfigurable annular slot based multiple-input-multiple-output (MIMO) antenna system integrated within an ultra-wide-band (UWB) sensing antenna. All the antenna elements are planar in structure and designed on a single substrate (RO-4350) with dimensions 60×120×1.5 mm3. The frequency reconfigurable slot based MIMO antenna system is tuned over a wide frequency band from 1.77 GHz to 2.51 GHz while the UWB sensing antenna is covering from 0.75~7.65 GHz The proposed antenna system is suitable for CR enabled wireless devices. The envelope correlation coefficient (ECC) did not exceed 0.248 in the entire operating band of the MIMO antenna part. The maximum measured gain of the MIMO antenna is 3.2 dBi with maximum efficiency of 81%.

Miniaturized, low power, wireless transmitter and receiver with on-chip antenna, and wireless coupling of on-chip and off-chip antennaShamim, Atif; Arsalan, Muhammad; Roy, Langis (2010-04-22) [Patent]A miniaturized, low power RF transmitter with a dual mode active on-chip antenna/inductor is disclosed in which antenna also serves as the oscillator inductor. Also disclosed is a miniaturized low power RF receiver with an on-chip antenna; and a RF transmitter system wherein an on-chip antenna is wirelessly coupled to an off chip patch antenna are disclosed. Advantageously, the TX chip is housed in a low loss, e.g. Low Temperature Co-fired Ceramic (LTCC) package with a patch antenna to provide a System-on-Package implementation comprising electromagnetic coupling between a RF TX chip comprising an integrated on-chip antenna and a package antenna. The on-chip antenna feeds the LTCC patch antenna through aperture coupling, thus negating the need for RF buffer amplifiers, matching elements, baluns, bond wires and package transmission lines, and significantly increases the gain and range of the module with respect to the on-chip antenna alone, without deterioration of the circuit performance and power consumption. Exemplary embodiments are disclosed which may be fabricated using standard CMOS technology, for operation in the 5 GHz U-NII band for applications such as miniaturized, low cost, low power wireless devices and sensor systems.
Antenna subset selection at multi-antenna relay with adaptive modulationChoi, Seyeong; Hasna, Mazen Omar; Yang, Hongchuan; Alouini, Mohamed-Slim (Wireless Communications and Mobile Computing, Wiley-Blackwell, 2011-06-01) [Article]In this paper, we proposed several antenna selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes were based on dual-hop relaying where a relay with multiple-antenna capabilities at reception and transmission is deployed between the source and the destination nodes. We analyzed the performance of the proposed schemes by quantifying the average spectral efficiency and the outage probability. We also investigated the trade-off of performance and complexity by comparing the average number of active antennas, path estimations, and signal-to-noise ratio comparisons of the different proposed schemes.

Integrated reconfigurable multiple-input–multiple-output antenna system with an ultra-wideband sensing antenna for cognitive radio platformsHussain, Rifaqat; Sharawi, Mohammad S. (IET Microwaves, Antennas & Propagation, Institution of Engineering and Technology (IET), 2015-06-18) [Article]© The Institution of Engineering and Technology 2015. A compact, novel multi-mode, multi-band frequency reconfigurable multiple-input-multiple-output (MIMO) antenna system, integrated with ultra-wideband (UWB) sensing antenna, is presented. The developed model can be used as a complete antenna platform for cognitive radio applications. The antenna system is developed on a single substrate area of dimensions 65 × 120 mm<sup>2</sup>. The proposed sensing antenna is used to cover a wide range of frequency bands from 710 to 3600 MHz. The frequency reconfigurable dual-element MIMO antenna is integrated with P-type, intrinsic, N-type (PIN) diodes for frequency agility. Different modes of selection are used for the MIMO antenna system reconfigurability to support different wireless system standards. The proposed MIMO antenna configuration is used to cover various frequency bands from 755 to 3450 MHz. The complete system comprising the multi-band reconfigurable MIMO antennas and UWB sensing antenna for cognitive radio applications is proposed with a compact form factor.
