“…The analysis has been done mainly among the flexible SWB or UWB antenna with extended bandwidth. It also includes some of the recent SWB antennas irrespective of the flexibility of the substrate [2,[12][13][14][15][16][17][18][19]. Since each of the reported SWB antennas are unique in design, their 10 dB impedance bandwidth is also different.…”

This study proposes a coplanar waveguide‐fed circular monopole antenna that is designed by ink‐jetting conductive silver particle ink on photo paper. The antenna comprises a slotted circular patch and a reduced symmetrically slotted ground plane that is etched rectangularly. The slotted circular patch and ground plane provide the design flexibility with a broad bandwidth, substantial gain over 1.66–56.1 GHz frequency band, and relatively consistent radiation pattern. The fractional bandwidth (%BW) of this antenna is 188.5% that is covering industrial, scientific, and medical (ISM) bands, ultra‐wideband, wireless local area network (WLAN) band, worldwide interoperability for microwave access (WiMAX) band, and various frequencies of upcoming fifth‐generation technology. The total size of the antenna is only 34 × 25 mm2, with an electrical dimension of 0.18 λ × 0.13 λ at 1.66 GHz. The bandwidth ratio (BR) is 33.81:1, and the bandwidth dimension ratio (BDR) is 7462, which is the highest among the flexible super‐wideband antennas reported so far. It is a low profile, lightweight, and low‐cost antenna that is accommodating a broad frequency spectrum for extended wideband communication. The measured results show good agreement with the simulations.

“…It has used a parasitic oval patched in the centre of the elliptical radiator and an elliptical tuning fork element as a feed line to achieve a percentile bandwidth of 163.4%. Many other reports exist on SWB antennas built on rigid materials [2,[13][14][15][16][17][18][19].…”

In this article, a compact super wideband (SWB) monopole antenna with a wide-frequency is designed and analyzed for future handheld gadgets. The designed antenna is made by etching four slots on a round cornered rectangular patch which are connected through a 50-Ω triangular tapered microstrip transmission feedline (TTMTF) for broadband impedance matching. A triangular slot is etched on the semicircular partial ground plane, which helps to shift the lower frequency edge of 1.07 GHz to 1 GHz. The experimental results show that the proposed antenna operates over a wide frequency range of 1-30 GHz with a reflection coefficient of less than −10 dB. The antenna acquires a compact dimension of 25 × 16 × 0.787 mm 3. Further, an equivalent circuit method is used to analyze the proposed structure, and its outcome is compared with the simulated and experimental results. The peak gain of the designed antenna is about 5.5 dBi. The proposed antenna has low cross-polarization even at higher frequencies. Finally, the time domain analysis is also carried out to see the distortion between transmitting and receiving modes. The designed antenna can be used for various wireless applications such as NB-IoT, GPS, Wi-BRO, ISM band, IRNSS, WiMAX, X-band, Ku-band, and K-band.

“…The complementary split ringresonator in the ground plane plus inverted U-shaped slot to block WiMAX, WLAN and X-band are presented in [21], while its BW is limited to 3.3-9.8 GHz, which is not covering the assigned frequency range for UWB. Recent researches are focused on designing antennas for SWB applications that include both shortand long-range communications [22][23][24][25][26].…”

A study of monopole antenna for super‐wideband applications is presented. A compact patch antenna is suggested to enhance the overall covered bandwidth (BW), where a major improvement of the BW obtained in the range 2.6–23 GHz (BW of 20.4 GHz). Also, by creating slots in the patch and in the feed line; three band‐notches are created to reject different narrowband applications. The different antenna parameters are studied using a high‐frequency structure simulator (HFSS). The measured data of the fabricated antenna shows good agreement with the simulated results with a slight shift at the lower and upper edges of the frequency range. A transmission line model of the proposed antenna is presented based on the effect of each element on the antenna behaviour. Advanced design system is used to construct and optimise the equivalent circuit model of the designed antenna. Results of the antenna behaviour obtained using the resistor–inductor–capacitor model compare favourably with the simulated results obtained using the HFSS both in the pass and rejection bands, with a small error at high frequencies.
