“…However, it affects the performance of the antenna and may slightly deteriorate the radiation patterns for each polarization. Various techniques in previous works have been developed to improve the impedance bandwidth of microstrip antennas [9]- [19]. For this purpose, utilizing the impedance matching networks [9], [10] and inserting the slots into the patch are taken into consideration as two common methods [11]- [13].…”

This study presents two new designs of reduced size broadband microstrip patch antennas for ultra-wideband (UWB) operation. A folded triangular patch’s feeding technique, V-shaped slot, half V-shaped slot and shorting pins are employed to design the suggested antennas. The shorting pins are applied at the edge of structures to miniaturize the size of the patches. The suggested design with the V-shaped slot provides the measured impedance bandwidth (S11˂-10 dB) of 3.91-12 GHz (101.7%) for broadband application. In the suggested design with the V-shaped slot, the wide bandwidth with an acceptable size reduction is achieved. By introducing a suggested half design with the half V-shaped slot, the impedance bandwidth of the proposed half structure is improved from 4 to 17.22 GHz. The half design includes a measured impedance bandwidth of 124.6% with reduced size of more than 93% compared to the corresponding full design and an enhanced measured bandwidth of 23%. The obtained radiation and impedance results show that the suggested designs are applicable for wideband operation. Besides, the effects of some basic concepts and surface currents on the suggested structures are investigated to explain their broadband performance.

This study presents a new stacked design of reduced size broadband microstrip patch antenna for ultra-wideband (UWB) operation. A folded triangular patch's feeding technique, half V-shaped slot and shorting pins are employed to design the proposed stacked antenna. Shorting pins are applied at the edge of structure to miniaturize the size of the patch. The proposed design with the half V-shaped slot and without stacked patch provides the measured impedance bandwidth (S 11 <−10 dB) of 115.7% (4.35-16.3 GHz) for broadband application. In the proposed design with the half V-shaped slot, the wide bandwidth with an acceptable size reduction is achieved. By adding a stacked element on the upper patch, the impedance bandwidth of the proposed antenna is improved from 3.47 to 17.35 GHz. The stacked design includes a measured impedance bandwidth of 133.3% with reduced sizes of more than 78% compared to the corresponding full design and an enhanced maximum gain of 6.2 dBi. The obtained radiation and impedance results show that the proposed design is applicable for wideband operation. Besides, the effects of some basic concepts and surface currents on the suggested structure are investigated to explain their broadband performance.
