For the transmission performances of the proposed OOK modulator, up to 10 Gb/s data rate is achieved from simulated results. However, limited by the demodulator, a data rate of only 2.5 Gb/s is measured. The demodulated waveform compared with the original PRBS-7 signal is shown in Figure 5. A $8 ns delay between the demodulated and original signal exist. Table 1 compares the performance of the proposed OOK fundamental modulator with the reported designs. Using 0.13 lm MOSFETs, this work realized terahertz band fundamental modulation with an IL of $4.9 dB and isolation higher than 13 dB, providing a great potential for terahertz gigabit-data-rate communications. CONCLUSIONA fundamental OOK modulator for terahertz high-data-rate communication application is designed and implemented using 0.13 lm MOSFETs. By adopting series loads, on-/off-switching is achieved with an isolation above 13 dB. The IL of the modulator is 4.9 dB and a 2.5 Gb/s data rate is demonstrated.ABSTRACT: This article presents a new design of ultrawideband monopole antenna with multiresonance and dual band-notched characteristics. The proposed antenna consists of a square radiating patch with a pair of step-shaped slits, a feed-line, and a modified ground plane with pair of rectangular slits and inverted coupled U-shaped parasitic structure. In the presented design, by cutting two rectangular slits and also by embedding an inverted U-shaped parasitic structure in the air gap distance, additional resonances are excited and hence much wider impedance bandwidth can be produced, especially at the higher band that the antenna provides a wide usable fractional bandwidth of more than 120% (3-13.7 GHz). To create a single band-notched property, a pair of step-shaped slits was cut at the square radiating patch. Finally, by converting the inverted U-shaped parasitic structure to the W-shaped structure, good dual band-notched function is achieved. The measured results reveal that the presented monopole antenna offers a very wide bandwidth around of 5-6 and 7.25-7.75 GHz to suppress any interference from wireless local area network and downlink of X-band satellite communication systems, respectively. The designed antenna has a small size of 12 3 18 mm 2 .

“…In this regard, to fulfill the base station requirements the planar inverted‐F antenna (PIFA) concepts are adopted in our study. The PIFA has inherent characteristics like its omnidirectional radiation pattern, its lightweight, and its low profile . Actually, there have been a several PIFA designs with different configurations to fulfill the multi‐band operation: Among the used configurations, we can state the branch line slits, the meandered shapes, the use of the slot technique as well as the use of parasitic elements .…”

In this article, a novel 3D meandered planar inverted‐F antenna (PIFA) is proposed for dual band application targeting Wireless Body Area Network (WBAN). The proposed antenna is printed on the casing of a 3D‐base‐station model having a size of 88 × 95 × 10.2 mm3. The proposed PIFA covers two bands including medical implant communication service (MICS) (402‐405 MHz), as well as the industrial, scientific, and medical (ISM) (2.4‐2.48 GHz) bands. Each of the two bands can be controlled independently. The 3D configuration contains two linked meandered resonators to downsize the structure. Due to its conformal shape, omnidirectional radiation pattern, and low‐profile nature, the proposed PIFA is a potential candidate for targeting the WBAN applications. The proposed antenna, covering the MICS and ISM bands, works with an optimally matching (VSWR<2) at the aforementioned bands. The design concept was validated by fabricating the antenna prototype and measuring its characteristics.

“…Since decades, microstrip‐fed patch antenna design has been largely adopted in wireless communication services, and these phenomena have made the microstrip antenna become more popular due to its flexibility, light weight, low cost, compactness and easy to fabricate . Microstrip antennas can be utilized in a number of applications such as digital or mobile communication services, wireless broadband, wireless local area network (WLAN) applications, and so forth . WLAN is a microwave‐based technology that runs on 2.4 and 5 GHz bands .…”

In this article, a dual‐band coplanar waveguide‐fed antenna is proposed for wireless local network. The dimensions of the antenna are 18 × 17 × 1.6mm3 fabricated on FR‐4 substrate. It comprises narrow hook shaped slits on left‐hand side and two separated ground planes. The measured results show that the proposed antenna has impedance bandwidth from 2.0 to 2.56 GHz and 4.59 to 6.0 GHz for 10 dB return loss. It can cover several wireless communication bands like UMTS 2100 MHz, Bluetooth 2400 MHz, WLAN 2400/5200/5800 MHz, and LTE 2300–2400 MHz bands. To validate the results of simulation, an inexpensive FR‐4 substrate is used for the fabrication of the prototypes of the proposed antenna and tested. Experimental and simulated results obtained indicate that the proposed antenna has good radiation efficiencies and near omnidirectional radiation patterns.
