الملخص

A mm-wave wideband compact transparent antenna is designed on Plexiglas substrate with dimension of 10.235x10x0.508 mm3 and then the ground plane is modified resulting in bandwidth enhancement. The proposed antenna achieves a bandwidth of 13.5 GHz and supporting two resonant frequencies at 24.7 GHz and 33.8 GHz with return losses of -35dB, and -33dB and gain of 6.4dB and 4.5dB respectively, in addition to achievable efficiency reaches up to 85%. The design is extended to two antenna elements with inverted U-slab shaped as a parasitic element introduced between antennas used for improving isolation and therefore reduce the mutual coupling. The separation between two elements is less than  resulting in isolation less than -39 dB with ECC is about 0.002 and diversity gain (DG) of 10 at the resonant frequency of 25.561 GHz to support 6 GHz of operating bandwidth. This result demonstrates a considerable improvement in antenna compactness, properties, and spectral efficiency; thereby it can be an excellent candidate to be used for 5G wideband applications and beyond.
