bandwidth can also be improved by loadin? of.3 Equivalent circuits The slot-loaded rectangular microstrip patch. antenna can be considered as parallel combination of capacitance C1, inductance L 1 and resistance R1 of patch and capacitive reactance of the slot, where R1, L~. C1 of patch are given... A compact slot antenna with improved bandwidth and gain… A wide-slot antenna is investigated to achieve a bandwidth of about 162%. The ground plane includes a rectangular slot with dual SRR and two semicircular defects in the bottom side of the rectangular slot. A fork like feed-line with two parasitic stubs to increase the bandwidth is used to feed the slot.

In this paper, a tapered slot antenna capable of ultra‑wideband communication was designed. In the proposed antenna, rectangular slits were inserted to enhance the bandwidth and reduce the area of the antenna. The rectangular slit‑inserted tapered slot antenna operated at a bandwidth of 8.45 GHz, and the bandwidth improved upon
