Abstract:
Data traffic consumption in wireless networks is increasing rapidly due to the ongoing usage of
wireless multimedia content. Telecommunications companies are starting to roll out fifth generation (5G) networks, which will use millimeter wave (mm-Wave) frequencies to give mobile
devices unprecedented bandwidth and multiple gigabits per second (Gbps) of data throughput.
This is done to meet the consumer's growing demand for data. 5G is expected to be up to ten times
faster than fourth-generation (4G) with speeds of up to 10 Gbps. In respect of antennas, this
translates into a large impedance bandwidth. High gain to reduce propagation losses, huge
bandwidth with increased reliability, and low latency are all requirements of the 5G
communications system. In this regard, wide band antenna is beneficial.
In this thesis, the designs of two wideband antennas are presented using substrate integrated
waveguide (SIW) features in millimeter-wave spectrum. The antenna’s slot topology ensures a
relatively wide impedance bandwidth and help to improve efficiency of the antennas. With taper
length of 8mm, the antennas are compact having size of 25×14mm2
. The proposed antennas have
-10dB impedance bandwidths from 35.883-42.358 GHz and 36.705-39.366 GHz respectively, as
well as good radiation efficiency, according to simulated and measured results. The gain of
antennas is around 10 dBi with radiations in single hemisphere. The antennas are strong contenders
for the usage in mm-wave communication as they satisfy the essential criteria for the 5G wireless
communication.
