Penta-band Circular Patch Antenna with Partial Ground for Wireless Applications

In this paper, a penta-band slotted antenna with a partial ground is proposed. The suggested antenna is used for different portable devices for wireless communication. The FR4-epoxy substrate which has a thickness of 1.5 mm is used to create an antenna with a partial ground. The frequency bands 4.1 - 5.2 GHz, 7.6 - 8.6 GHz, 10.5 - 11.7 GHz, 13.5 - 14.7 GHz, and 18.6 - 20.2 GHz are all covered by a proposed antenna. For each of the covered fractional bandwidths 23.91%, 12%, 10.81%, 5.67%, and 8.24% respectively. The proposed antenna covers the application of Wi-Fi, Bluetooth, S-band, C-band, K-band, Ku-band, and X-band. The maximum gain of 4.7 dB is achieved by a proposed radiator for a higher band. The performance of an antenna makes it clear that it is good for wireless applications.
