“…Placing a parasitic slot-shaped patch into the middle of a printed antenna can further increase the bandwidth from 2.23 to 5.53 GHz [9]. Tuning stubs [10] are optimized to further improve the bandwith based on the antenna design in [9]. Different shapes of the tuning stubs are investigated in [11] to generate a series of different bandwidths.…”

This paper proposes a self-shape blending algorithm to improve antenna bandwidth. A printed antenna is designed for bandwidth enhancement based on the proposed algorithm; this approach can also be used to enhance bandwidth in other applications. The antenna completely covers WLAN bands and WiMAX bands after the proposed algorithm is applied. The shape of the rotating slot and the parasitic patch also changes, which excites additional resonance and improves the impedance matching at high frequencies. Test results show that the proposed antenna can work from 2.07 GHz to 5.94 GHz with S 11 ≤ − 10 dB . Compared to a slot antenna without the self-shape blending algorithm, the bandwidth increases by more than 0.7 GHz.

“…But an RLBW ranging from 2.23 to 5.35 GHz is obtained. A similar configuration but having two matching stubs for better impedance matching over a wide range of frequencies ranging from 2.38–9.64 GHz is reported in Reference . By shifting the feed line and truncating the corners of the wide‐slot, a large RLBW of 108.2% has been obtained .…”

In this study, a novel printed wide‐slot antenna for wideband applications is presented. The designed antenna consists of four merged elliptical wide‐slots (EWSs) of different dimensions in the ground plane. An open‐ended microstrip line having a characteristic impedance of 50 Ω is used to excite the EWS. Each EWS corresponds to the different frequency of operation and hence when merged together give a wideband response. The fabricated prototype of the designed antenna shows the 10 dB return loss bandwidth (RLBW) of about 157.72% ranging from 2.21 to 18.7 GHz. The peak gain varies from 0.1 to 6.5 dB within the RLBW is reported. An almost constant group delay, low variation (<−40 dB) in the transfer function S21 and linear phase variation for both side by side and face to face orientations of the designed antenna shows its applicability for wideband applications. The electrical dimensions of about 0.176λ L × 0.162λ L (where λ L is the lowest operating wavelength) give rise to the bandwidth dimension ratio of about 5505 which is highest among the antenna structures reported in the literature. The measured results are found in good concordance with the results obtained from numerical simulations.

“…Another way to enhance the IBW is to use parasitic patch along with the wide-slot as discussed in [15]. Along with the parasitic patch, Kwame et al [16] added a pair of tuning stubs to the microstrip feed line for broadband operation. In [17], the wide slot of Minkowski shape is used and significantly high bandwidth of 73.14 and 69.42% in first and second iterations has been obtained respectively.…”

The antenna designs discussed in [6][7][8][9][10][11][13][14][15][16][17] are well enough to meet needs of various wireless applications, but either they are too complex to design or too large to fit in applications where limited space is provided for antenna systems.…”

This study presents two design improvements over conventional microstrip antenna in terms of multiband operation, gain and cross‐polarisation (XP) level. The first design (Type‐I) consists of a microstrip line on one side and an elliptical slot (ES) on the other side of the substrate. The second design (Type‐II) consists of a parasitic elliptical patch inside the ES in addition to the first design. A theoretical analysis using an equivalent circuit model is performed for both antenna designs for estimating the dimensions of each part of the proposed structures. It is found that the size of the wide ES determines the lower operating frequency, whereas coupling between the parasitic patch and microstrip line decides the multiband operation. Experimental results show that the Type‐I antenna resonates in three frequency bands at 2.49, 3.7, and 9.76 GHz with peak gain and XP level of 8.66 and 44.43 dB, respectively. With proper selection of the dimensions of the parasitic patch, the Type‐II antenna generates five frequency bands at 1.87, 6.42, 10.76, 12.67, and 13.66 GHz. An exceptionally high gain of 16.79 dB with an XP level of 36.15 dB is reported in Type‐II antenna. The theoretical and simulation results show a good agreement with the measured results.
