“…Currently, piles of wideband dual-polarized antennas have been proposed in [2][3][4][5][6][7][8][9][10][11][12][13]. Cross dipole antennas in [2][3][4][5] and patch antennas in [6][7][8] are two classic wideband antenna types. In the design of [9], a dual-polarized antenna with wide operating band, high port isolation and good radiation performances is proposed by loading some dipoles.…”

In this paper, a wideband ±45 • dual-polarized antenna is proposed for the wireless communication. An annular ring patch with four arc-shaped slots is employed to generate a wide operating impedance bandwidth. By introducing four open stubs to the antenna element, the impedance bandwidth is enhanced. The antenna has a broad impedance bandwidth (VSWR < 2) of 51.2% (1.63-2.75 GHz) and a high port-to-port isolation of 27 dB over the entire band of operation. In addition, a 1 × 4 antenna array is developed for the wireless communication. Experimental results illustrate that the antenna array features wide operational bandwidth, high port isolation and superior radiation performance.

“…The first signal by IQ modulation in transmitter directly passed the SPDT switch. In the ideal state, if the measured bit error rate is 0, the demodulated signal constellation distribution will be concentrated in [−1,0] and [1,0], which means the correctness of the system design. (2) Design the transmitter and the receiver separately to get the radio link budget.…”

“…For an ideal communication system without any noise or interference factors, the demodulated constellation should be fixed at [1,0] and [−1, 0], as is shown in Figure 10b. However, in Figure 10a, the demodulation constellation points are uniformly scattered around [1,0] and [−1, 0], which can be explained by the additive Gauss white noise, non-idealization of antennas and other components in the system. the dotted line compares the channel capacity of the single input single output (SISO) systems.…”

This paper introduces the principle and key technology of single radio frequency (RF) link Multiple-Input Multiple-Output (MIMO) system based on a switched parasitic antenna (SPA). The software SystemVue is adopted for signal processing and system-level simulation with merit of strong operability and high efficiency, which provides tools for the single RF link MIMO system research. A single RF link of a 2 × 2 MIMO system based on the switch parasitic antenna is proposed in this paper. The binary codes are modulated to the baseband Binary Phase Shift Keying (BPSK) signals and transmitted with a 2.4 GHz carrier frequency. The receiver based on the super-heterodyne prototype adopts the channel equalization algorithm for restoring symbols, and it can effectively reduce the system error rate. The simulation results show that the MIMO system built on the platform can achieve equivalent performance with traditional MIMO system, which validates the effectiveness of the proposed scheme. The switched parasitic antenna and equalization algorithm provide new research ideas for single RF link MIMO system and have theoretical significance for further research.

Abstract-This paper presents two novel miniaturized broadband Quasi-Yagi antennas which adopt compact layouts and two different modified bowties as driven dipoles. In these antennas, the microstrip feed and λ/4 impedance transformer are placed horizontally and rearranged in a same horizontal line with balun to reduce the vertical size. The horizontal size is reduced by loading the vertical metallic strips at the sides of bowtie driven dipole and ground patch. Compared with the conventional QuasiYagi antenna, the sizes of the two proposed antennas are decreased to approximately 50%. The experiment results exhibit that they have wide bandwidths of 2.27-3.35 GHz and 2.14-3.3 GHz for reflection coefficient below −10 dB. Their gains reach 4 dBi over the operation frequency band, which indicate that they can be applied conveniently in wireless communications and recognition fields like WLAN, RFID, WiMAX and LTE frequency bands.
