“…These antennas cover a dual broadband with advantage of average compact substrate dimensions of 33 × 32 mm 2 . A planar monopole microstrip antenna loaded with composite right/left-handed transmission line (CRLH-TL) for broadband LTE mobile phone was proposed, analyzed and fabricated [12]. This antenna covers LTE700/2500, GSM850/900/1800/1900, UMTS2100 and WLAN2400 frequency bands, and it is etched on a single substrate of dimensions 16 × 60 mm 2 .…”

In this paper, two compact and broadband microstrip monopole antennas have been proposed, designed, and presented using two novel sets of design equations. Each monopole antenna design has different dimension and characteristic. The proposed designs have been verified using a commercial electromagnetic simulator (CST-Studio) and implemented prototypes mounted on FR-4 substrate having a thickness of 1.6 mm. In addition, a linear array consists of only two monopole elements has been designed and presented to enhance the gain of the proposed monopole antenna. Simulation results confirmed the validity of the two novel sets of design equations for both monopole and array antennas. Also, the proposed array antenna (38 × 36 mm 2 size), achieved a moderate gain of (6.0 dBi), a satisfying efficiency of (81%), a VSWR that is less than 1.2 and a 22% fractional bandwidth of about 1200 MHz. Moreover, simulated and measured return losses of the proposed monopole antennas (single and array) accomplish a reasonable agreement. The proposed monopole antennas are simple designs and compact in size, and they can be used for many wireless applications including WiFi, LTE, and WiMax. In addition, a compact array of large monopole number can achieve a higher gain that is up to 18 dBi (four to eight monopole array elements with overall size 38 × 72 mm 2 to 38 × 144 mm 2). The novelty of this paper is by introducing the proposed and closed form design equations for a monopole introducing the length of monopole and ground of substrate dimensions as a function of r and thickness.

“…The full‐wave simulated results obtained from Ansoft‐HFSS and measurement results agree very well with the proposed theories. On the contrary of the other designs that include LTE13 which suffer from low efficiency at this band, our design have very good efficiency. Meanwhile, it prepares 40% size reduction in comparison with a common dipole.…”

In this article, we apply a novel fractal in arms of an antipodal dipole for antenna miniaturization that uses the Chu's sphere very effectively to keep antenna efficiency very high in comparison with its counterparts like Koch dipole/monopole. Then, a formula is extracted to determine the first resonance of the dipole. We used this method to design a mobile antenna at LTE13 band (746–787 MHz) which is well known for leading the size of a common dipole antenna to be very large for a handheld mobile. The proposed design shows 40% size reduction in comparison with a common dipole while antenna efficiency is better than 79.28% with S11 greater than 10 dB. It also covers LTE band2 (1850–1990 MHz) with S11 and efficiency better than 6 dB and 78.91%, respectively. The overall size of the printed antenna is 62 × 115 × 1.6 mm3. The simulation and measurement results verify the presented calculations very well. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2429–2434, 2015

Limited space is given to antennas in modern portable wireless systems, which means that antennas need to be small in size and compact structures. However, shrinkage of conventional antennas leads to performance degradation and complex mechanical assembly. Therefore, the design of miniature antennas for application in wireless communication systems is highly challenging using traditional means. In this chapter, it is shown that metamaterial (MTM) technology offers a solution to synthesize antennas with a small footprint with the added advantage of low cost and excellent radiation characteristics.
