“…Moreover, in the H ‐plane pattern, a higher cross‐polarization component ( E θ ) is observed which may be due to the radiation from the nonradiating edges of the partial ground plane of the antenna. Moreover, since the studied antenna is fabricated on a microwave substrate with a high dielectric constant, this cross‐polarized component becomes significantly prominent near the bore‐site direction in H ‐plane which is reported in Bhartia et al, 26 Siddique et al, 27 and Azim et al 28 Despite the high cross‐polarized field in H ‐plane, from the plot, it can be commented that the radiation patterns of the anticipated antenna are symmetrical and omnidirectional which is a primary requirement of various wireless communication applications.…”

Summary Recently, there is a significant rise in the numbers of devices and systems that use industrial, scientific, and medical (ISM) frequency bands. The ISM band is not only used in ISM applications but also in telecommunication services including IMT, Zigbee, Bluetooth, WiFi, WiMAX, WLAN, RFID, military radars, and wireless sensor networks. To cover all these applications, in this paper, a low‐profile planar monopole antenna is suggested for 2.45‐GHz band communication applications. The anticipated antenna is composed of a vertical bar‐shaped radiator and a partial ground plane with two vertical slits. The inclusion of vertical slits in the ground plane forms a matching circuit by enlarging the current path, and hence, the studied design can achieve a measured operating band of 2.2 to 2.95 GHz. Moreover, the studied antenna achieved a maximum peak gain of 2.77 dBi and a maximum radiation efficiency of 82.45% and exhibited an omnidirectional radiation pattern that makes it appropriate for ISM and different narrowband wireless applications.

“…It can be observed from the Table 2, that proposed antenna is compact in size and exhibit higher value of negative gain at both rejected frequency band as compared to the other references except reference. Also, the VSWR bandwidth of proposed antenna is more in comparison to references [30–36, 38, 39, 41‐43], except references [40,44,45]. While, the bandwidth (VSWR ≤2) of references [40,44,45] is better but the size of antenna designed in these references is large in comparison to the proposed UWB antenna.…”

A compact ultra‐wideband (UWB) printed monopole UWB with dual band‐notched characteristics has been designed and investigated in this manuscript. The Wi‐MAX and wireless local area network (WLAN) band rejection characteristics have been obtained by employing the circular ring and arc‐shaped slot along with rectangular slot in radiating patch. Overall size of proposed UWB antenna is 27 × 27 × 1.6 mm3, which consists of sprocket gear wheel shaped structure as a core radiating patch element and excited by using 50 Ω coplanar waveguide feed. The proposed antenna exhibits the UWB frequency spectrum from 3.1 to 10.6 GHz along with Bluetooth frequency range 2.4–2.48 GHz without disturbing overall dimensions of antenna. Proposed antenna reveals the measured VSWR operating bandwidth of 10.0 GHz in the frequency range from 2.0 to 12.0 GHz along with Wi‐MAX and WLAN rejected bands. Moreover, proposed antenna adorns the measured gain of −8.28 and − 9.98 dBi at rejected frequency bands, whereas, at other frequencies, it changes between 1.5 and 5.0 dBi. The radiation efficiency of proposed UWB antenna varies from 84% to 97% except rejected frequency bands. Group delay and radiation pattern have also been analyzed and found appropriate for the current UWB applications. Finally, the optimized structure of antenna with dual band rejection characteristics has been fabricated and tested for the authentication of simulated results. Both the results are compared and are found in good agreement with each other.

“…Moreover, as the studied antenna is prototyped on substrate material with higher thicknesses and large dielectric constant, this cross-polarized radiation becomes significantly prominent near the broadside direction which reflects the finding reported in Refs. [14][15][16]28 . This higher cross-polarized level and distortions can be suppressed using modified feeding arrangement, exploration of defected patch surface, use of the shorted patch, use of microwave absorbers, and metamaterials.…”

Due to the rapid development of wireless communication systems, good numbers of services and devices use different frequency bands and protocols. To concurrently cover all these services, the antenna in communication devices should operate over multiple frequency bands. The use of wide and multi-band antennas not only reduces the number of antennas necessary to cover multiple frequency bands but also lessens the system complexity, size, and costs. To operate over eight frequency bands to cover sixteen well-established narrow service bands, a planar monopole antenna is proposed for portable communication devices. The proposed antenna is comprised of an inverted F-shaped monopole patch with a rotated L-shaped strip and an F-shaped ground strip with a rotated L-shaped branch. The studied antenna can excite at multiple resonant modes which helps it to achieve eight measured operating bands of 789–921 MHz, 1367–1651 MHz, 1995–2360 MHz, 2968–3374 MHz, 3546–3707, 4091–4405 MHz, 4519–5062 MHz and 5355–6000 MHz. The achieved measured operating bands can cover sixteen popular narrow service bands for 4G/3G/2G, MWT, WiFi, WiMAX, WLAN, and sub-6 GHz 5G wireless communication system. The studied antenna achieved good gain, efficiency and exhibits stable radiation characteristics. Moreover, the antenna does not use any lumped element and left ample space for other circuitries which makes it easier to use in portable devices such as tablets, laptops, etc. with low manufacturing cost.
