High Bandwidth

The requirement to serve more users and provide more data at more incredible data speeds drives demand for wireless wideband communications. The Ultra-Wide Band (UWB) technology uses nanosecond-long pulses to span an extensive frequency range. The high bandwidth, low power consumption, and less fading due to multipath are attained in UWB communication technologies. This paper explains a hexagonal monopole antenna design using a high-frequency structure simulator (HFSS) and is further optimized for c better bandwidth. A hexagonal monopole antenna is designed using FR-4 epoxy metamaterial substrate. The optimum hexagonal bandwidth is attained at a span of 6.13 to 7.34 GHz frequency, and the polar gain is 1.2 dB. This paper provides the UWB antenna design; an optimized bandwidth is achieved as expected, the applications of smart marketing and a discussion of all relevant literature are carried out.

Measurement Analysis

This chapter mainly focused on the recent trends in the antenna design techniques for next-generation wireless communication systems. Ultra-wideband antenna and multi-input-multi-output antennas are very useful to achieve higher data rates. An antenna is a transducer that changes guided electromagnetic energy in a transmission line to radiated electromagnetic energy in free space. Antennas may also be observed as an impedance transformer, coupling among an input or line impedance, and the impedance of free space. The looming widespread commercial deployment of ultra-wideband (UWB) systems has flashed new interest in the subject of ultra-wideband antennas. The power levels approved by the FCC mean that every dB counts in a UWB system as much as or possibly even more so than in a standard narrowband system. Thus, in effect, UWB antenna is a precarious part of an overall UWB system design. Basic principles for ultra-wide-band (UWB) antenna design and radiation are presented and discussed in this chapter.

Rectangular Patch

A compact rectangular MS antenna for Ultra Wide Band applications is designed. In the proposed design the rectangular patch antenna designed with cutting a slot in ground of length and width 2.5mm and 3.0mm respectively at the back of feed line. By using the defective ground plane a wide BWof 9.782 GHz with frequency band 3.099 GHz to 12.278 GHz is achieved. The designed antenna with a compressed size of 30 mm x 30 mm is fabricated and tested. The antenna’s return loss and VSWR plots are presented here to confirm the complete UWB bands. Special configuration of patch antenna with slotted partial ground was designed and optimized using CST Microwave Studio.

Sensing Applications

A spectrum-sensing algorithm is used to detect the available and the occupied frequency bands. The wideband antenna design approach is used for a microstrip fed monopole antenna that can be used for various wireless technologies such as GSM, UMTS, LTE, and WiFi operating at different frequencies from 1.25 to 3 GHz. The antenna is constructed from two copper layers of rectangular radiator and a partial ground plane. These layers are printed on an RO4003 substrate with dimensions 60 x 80 mm2. The antenna is experimentally fabricated to verify the simulation predictions and good matching between simulated and measured results is achieved. The wide-band antenna is tested by connecting it to the receiver of the Blade-RF Software Defined Radio (SDR) platform. A matlab script is then used to control the SDR board and to perform Spectrum Sensing for Cognitive Radio Applications.
