A frequency reconfigurable planar monopole antenna for fifth-generation (5G) mobile communication terminal equipment is presented. The proposed antenna uses a meandered monopole, branch resonance and other techniques to make the antenna resonant in multiple frequency bands. The antenna is compact in size (115 mm × 55 mm × 0.8 mm) and has a longitudinal length less than one-tenth of the resonant wavelength (working at 1.79 GHz). The pin diode is designed between the planar meandered monopole antenna and branch. The current path of the high-frequency current on the antenna can be easily controlled by controlling the DC bias voltage of the diode, and the operating frequency of the antenna is switched between three frequency bands. The antenna is fed directly through a 50 Ω matched transmission line. The measured data of the antenna in the anechoic chamber show good consistency with simulation data. The radiation pattern of the antenna shows good omnidirectional characteristics and good frequency characteristics, with a maximum radiation gain of 13.6 dBi. Experimental results demonstrate that the antenna can meet the design requirements of 5G communication.

5G Mobile Communication

As a convenient and efficient public transport system, high speed railway (HSR) was rapidly deployed in China. Since the fifth generation (5G) mobile communication system is commercially applied, it is necessary for mobile terminals antennas to cover multiple operating bands to be compatible with various communication systems. Here a HSR-mounted broadband and high-gain monopole antenna is proposed. By using the meander technology and introducing the tapered structure, the proposed antenna operates over a bandwidth of 694-960 MHz and 1350-5975 MHz (VSWR<1.8), which covers both 2G-5G mobile communication and WiFi frequency bands. The dimensions of the proposed antenna are 400 mm × 330 mm × 78 mm. The measured average gain is 6.11 dBi over the entire bandwidth.

A novel multiband-printed planar monopole antenna for LTE multi-input and multi-output (MIMO) application is proposed. A meandering microstrip line-loaded monopole antenna with multiband characteristic is presented. The proposed antenna provides five frequency bands for LTE application, covering 0.7, 1.7, 2.1, 2.3, and 2.5 GHz. In order to provide low mutual coupling and envelope correlation, two of the antennas are combined with orthogonal polarizations. The mutual coupling of the antenna is lower than −13 dB across the operation bands. Both the simulated and measured results are shown to illustrate the performances of the proposed antenna.

Service Bands

AbstractDue 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.
