“…Recent years by more demands on mobile communication, indoor wireless networks consisting of several indoor base station antennas have been mounted on many ceiling of buildings . Several researches have focused in sleeve monopole antenna for wide impedance matching for DTV and GSM application . The proposed dual sleeve monopole antenna in this paper can cover all of DTV (470–862 MHz), GSM (824–960 and 1710–2170 MHz) and WiMAX frequency bands as its compact structure.…”

This paper presents a dual sleeve monopole antenna that covers Global System for Mobile Communications (GSM), worldwide interoperability microwave access (WiMAX), and wireless local area network (WLAN) frequency bands. This new antenna is more wideband and compact structure in compare to other works. Simulation is done by Ansoft HFSS14 and results show the proposed omnidirectional antenna, ranging from 360 MHz to 5.1 GHz that bandwidth is 174% for return loss below −10 dB. The height of structure is 0.16 λ that has been achieved size reduction about 35% in compare to conventional monopole antenna with height 0.25 λ. These characterizations make this antenna very beneficial for jammer application. Jammers make places more secure and comfortable by reducing cell phones disruptions from some public places. The prototype of this structure has been made and the measure results are in good agreement with simulation results. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1271–1277, 2017

“…Several wideband antennas have been proposed in these bands [3]. In [4], an asymmetric fork-like printed monopole antenna is presented for DVB-T application, which achieves a -10 dB bandwidth of 451-912 MHz but with a size of 247×35 mm 2 . In [5], an UHF wideband printed monopole antenna has been introduced with dimension of 120×240 mm 2 .…”

The demand for spectrum resources has increased dramatically with the explosion of wireless mobile devices and services. The Cognitive Radio (CR) associated with TV white space frequencies defined between 470 MHz to 790 MHz is one solution to excel the spectrum resources shortage and address LTE low bands. The antenna design to cover such a wide band is a twofold challenge. First Electromagnetic fundamental limits impose a tradeoff between antenna efficiency, miniaturization and its frequency band wideness, secondly to be implemented in portable device (around 10 cm typical length) the antenna miniaturization needs is to be strong such as in λ/6 (where λ is the wavelength at 500 MHz). Thus, frequency reconfigurable antennas are suitable candidates and can be easy integrated. In this paper a compact frequencyagile notch antenna for LTE low-band using TV white space frequencies is designed and fabricated. The 18 x 3 mm notch size (area dedicated for the antenna) is only λ/33 at 500 MHz. The antenna aperture tuning is provided by a SOI CMOS tunable capacitor. The novelty of this paper is to present not only classical metrics (gain, return loss…) but also the experimental characterization of parameters that are usually used for active RF components. The non-standard tunable capacitor RF non linearity analysis is carried on and analyzed. The simulated and experimental performances are presented and demonstrate antenna tuning operation from 800 MHz down to 500 MHz. The slot electrical near field distribution is also investigated to confirm acceptable electrical field within the tunable component. High linearity is validated with measured ACLR levels lower than -30 dBc up to 22 dBm input power in the considered frequency range.

“…Transition from analog TV to digital video broadcasting (DVB) has increased the demand for compact size, low‐profile antennas that cover the DVB bands: 470–862 MHz and 1452–1492 MHz [1]. Several techniques were reported in the literature [2–4]. Among them are meander line antennas, which can provide physically small, however, electrically large antennas [5–8] and up to 1:8 bandwidth [7, 8], conformal conical‐based monopole antennas that can achieve 200‐MHz resonant frequency; however, the length is longer than 15 cm with less impedance bandwidth, and printed 2D monopole antennas that provide compact size; however, they exhibits a shift in the operating bands and an impedance matching that is worse than the three‐dimensional (3D) monopole [9].…”
