A compact differentially fed dual‐polarized patch antenna with filtering performance is proposed for 5G applications. By utilizing the half‐wavelength standing current along the open‐ended microstrip line, the out‐of‐phase output signals are obtained. Utilizing the E‐shaped coupled resonator in series with the open‐ended microstrip line, balanced differential feeding with filtering property are realized, as excitation for the patch. The filtering patch antenna was fabricated for demonstration. Measured results show that the antenna has −15 dB impedance bandwidths of 13.7% (3.26–3.74 GHz) and 14.2% (3.25–3.75 GHz) for two polarizations, respectively, covering the 5G band (3.3–3.6 GHz). The patch antenna achieves good port isolation and cross‐polarization discrimination. In addition, the measured gain is higher than 6.8 dBi within operating band. Out of the operating band, the gain drops sharply, exhibiting a bandpass response. The out‐of‐band radiation suppression level of the proposed filtering patch antenna is larger than 16 dB.

“…Differential topology is widely applied in constructing microwave circuits and systems because of its high immunity to noise and crosstalk. Corresponding to this trend, many devices have been designed in differential configuration, such as power dividers, 1,2 phase shifters, 3,4 antennas, [5][6][7] and filters. [8][9][10][11][12][13] In earlier works, the differential bandpass filters (BPFs) have been extensively developed by using various technologies, such as the printed circuit board, [8][9][10][11] the low temperature co-fired ceramic, 12 and the substrate integrated waveguide.…”

This letter presents a novel miniaturized differential dual‐band bandpass filter (BPF) using a single quad‐mode metal‐loaded dielectric resonator (DR). The differential dual‐band BPF is designed in a single‐cavity configuration with one quad‐mode DR and four feeding probes, featuring compact size. The rectangular DR is directly mounted on the bottom of the metal cavity and covered by a metal plate on the top surface. It allows two pairs of orthogonal modes (LSE10 and LSM10), which can be differentially excited and coupled by introducing proper perturbation for constructing dual‐band differential‐mode frequency response. To validate the proposed idea, a compact differential BPF with good performance using a quad‐mode DR cavity is designed, fabricated, and measured. The simulated and measured results with good agreement are presented.

“…This problem can be solved by using a differential design with high Common-Mode Rejection Ratio. For improved performance, existing literature introduces complex structures, like stacked designs or stub designs, making them impractical for consumer type applications [13,14]. Moreover, even though dipoles are differential in nature, differential characteristics are not well studied, and most of the configurations are single ended with a built in balun for single ended characterization.…”

In this letter, a tuning fork shaped, differential dipole antenna, with two floating reflectors, is presented. The dipole antenna resonates at 1.22 GHz and has a fractional bandwidth (FBW) of 16.39% and a differential impedance of 100 Ω. The proposed antenna is composed of quarter wavelength tuning fork shaped dipole arms in the top layer. To improve robustness, while connecting to the differential circuits, two floating reflectors are used on the bottom layer, beneath the dipole arm. This method helps improving the gain by 7%. A microstrip-to-coplanar strip line (CPS) transition is designed to measure the stand-alone differential antenna. The measured gain and efficiency of the antenna are 2.14 dBi and 84%, respectively, at the resonant frequency. The possible targeted applications are circuits with differential inputs/outputs, like energy harvesting circuits, radio frequency tags, wireless communications and any other wireless sensor network nodes. Details of the design along with simulated and experimental results are presented and discussed.
