“…Another factor limiting the widespread use of THz technology is high attenuation path loss in the THz spectrum . As a solution to attenuation problem, researchers have investigated several high‐gain antenna structures such as Yagi‐Uda, log‐periodic, bow tie, on‐chip antenna, microelectromechanical systems antenna, metamaterial‐based antennas, substrate‐integrated wave guide antennas, leaky wave antenna, lens antenna, and wideband horn antenna . All the above discussed geometries had three‐dimensional complex and large geometries.…”

An elliptical microstrip antenna for ultrawideband applications in terahertz (THz) frequency range is proposed. It comprises a microstrip feedline and a partial rectangular ground plane. It has an operating bandwidth of 0.46‐5.46 THz and a peak realized gain of 12 dB. It is simulated by using both high‐frequency structure simulator (HFSS) and Computer Simulation Technology Microwave Studio (CST MWS) simulators. It has distorted omnidirectional radiation patterns across the entire band of operation.

“…Tapering line sections are designed to match the designed leaky wave structure to the feeding microstrip line. On the other hand, mm-wave leaky wave antennas are good candidates for different applications like radars [14], real time spectrum analyzers [15] and 5G mobile communications [16] [17]. In addition SIW is a good technique for implementing these mm-wave leaky wave antennas.…”

In this paper we present the design of a leaky wave antenna based on Substrate Integrated Waveguide (SIW) loaded by Complementary Split Ring resonator (CSRR). The proposed antenna is designed for 5G application with a center frequency around 28 GHz. The antenna is implemented on Roger RT/Duriod 5880. The loading CSRRs are designed to resonate at 28 GHz. The design is simulated by using both High-Frequency Simulation Software (HFSS) and Computer Simulation Technology (CST) for verification. Experimental measurements are also presented.

“…To meet this expected requirement, a new fifth generation (5G) mobile network has been proposed [4][5][6]. As the available bandwidth at low frequency is overloaded and unable to satisfy the required wide bandwidth of 5G, many international organisations have suggested or licensed the mm-Wave spectrum to be the operating frequency of 5G including at 24, 28, 37, 39, and 60 GHz [7][8][9][10].…”

“…Therefore, for mm-Wave 5G, it is strongly expected that MIMO technology, which has already been used by 4G, will be one of the most compelling components of the mobile network [52]. As mentioned earlier, many international organisations have suggested or licensed the mm-Wave spectrum as the operating frequency of 5G, including 24, 28, 37, 39, and 60 GHz [7][8][9][10]. To that end, it is paramount to evolve smartphones to incorporate mm-Wave 5G antenna with existing sub-6-GHz antennas inside the handset, as exemplified in Figure 2.4.…”

The use of bandwidth for mobile and cellular networks has been increasing at an unprecedented rate, with applications in emergent areas such as smart vehicles and civil infrastructure, telemedicine, and remote education. The predicted increase of mobile network utilisation requires a high data rate capacity to transfer information through the network. The current limited capacity of the fourth generation (4G) mobile network is not expected to satisfy the predicted high data demand by 2020. To meet this requirement, a new fifth generation (5G) mobile network has been proposed. In order to reach the high capacity demands, the 5G requires a wide frequency bandwidth, which is not available in the sub-3 GHz frequency spectrum. Therefore, many international organisations have assigned the millimetre-wave band (mm-Wave), which includes 24, 28, 37, 39, and 60 GHz, as a frequency band for 5G. Using mm-Wave raises many challenges such as an increase in the path loss, radiation field absorbed by the human body, signal polarisation misalignment, and MIMO antenna footprint inside the mobile handset. Therefore, designing beam-steering, reconfigurable circular polarization, and compact MIMO antenna systems for 5G applications is important to cope with these challenges. Although there are some antenna systems were reported recently for mm-Wave 5G, they had limited steering angles, one polarization types or bulky antenna size. This thesis aims to solve the current challenges mentioned above by developing mm-Wave 5G antenna systems and in doing so makes three main contributions to the field of mm-Wave 5G antenna systems.
