Design and development of uwb patch antenna with variable band notched using ring-shaped slits
ASEAN countries have recently proposed the frequency band (4.5–5.5) GHz for fifth generation (5G) cellular communication, which necessitates the creation of an ultra-wideband (UWB) antenna to accommodate the band-notched function.

| Summary: | ASEAN countries have recently proposed the frequency band (4.5–5.5) GHz for fifth generation (5G)
cellular communication, which necessitates the creation of an ultra-wideband (UWB) antenna to
accommodate the band-notched function. To describe the compact shape of a UWB antenna in the context
of 5G application, this article has introduced a variable notched resonant characteristic at 5G lower band. A
tuning fork radiating patch with a simple defected ground plane structure was used to create the UWB
antenna. In order to create the band-notched criteria, a pair of ring-shaped slits (RSS) has been applied to
the ground plane. This antenna has achieved a huge bandwidth from 2.9 GHz to 11 GHz and an extremely
low VSWR less than 2. It appears that the antenna covers all frequencies except for notched frequency
bands at lower 5G band (4.5–5.5) GHz. The antenna has been archived a peak gain of 5 dBi for UWB, but
the notched frequency band produces less than -1 dBi. The notched-band can be shifted gradually in
response to changes in the different positions of RSS’s along the vertical axis, resulting capability to design
for variable band-notched characteristics. The preliminary design was presented in [19]. The complete
design is fabricated and tested and presented in this paper. The proposed antenna is small, with a surface
area of 45×34 mm2, making it ideal for 5G lower band application. |
