“…11 Dielectric resonator antenna (DRAs) and quasi-planar dielectric stacked patch array (DP) is also proposed for wide frequency tuning and beam scanning application. 12,13 These 3D antennas also exhibit exceedingly low gain and limited to discrete or 1-D beam scanning. In general leaky wave antennas (LWA) attain beam scanning capability with varying frequency.…”

In this work a low profile (<0.01λ0), single layered, high gain reduced sidelobe miniaturized microstrip planar array operating at higher-order broadside mode (HOM) with frequency tuning and 2-D beam scanning ability is proposed. The gain is enhanced significantly by array configuration using elements operating at TM03 mode. A rectangular slot is etched in the middle of the patch to reduce the side-lobe level (SLL) below À15 dB in both principal planes. λ/2 parabolic shaped current linkages are connected between the outer λ/2 patch strips supporting TM03 mode to reduce the non-resonant length from 1.5λ to 1.167λ; hence minimizes the patch area by 22%. A 2 Â 2 miniaturized planar array is designed at 2.45GHz using these elements; hence reducing the array footprint. Frequency tuning mechanism is incorporated by placing varactor diodes on the radiating edges of the array elements. Also 360 beam switching at azimuth plane and ± 40 (including 3 dB beam width) at elevation plane is achieved by suitably detuning the varactor capacitances. The simulated and measured results are found to be consistent throughout the 10% frequency tuning range. Maximum 17.1 dBi realized gain is measured which remains consistent within 2 dBi variation for entire frequency tuning and beam scanning range.

“…The era of 5G/B5G promotes the development of wireless communication systems, which put forward higher demands for RF front-end devices [1]. Miniaturization, integration, multifunction and high performance have become the development trend for RF front-end [2]- [5]. Differential microstrip antennas, as one of the most vital RF front-end devices, not only have the advantages of low cross-polarization level and high common-mode (CM) suppression, but also can interconnect directly with differential circuits or systems, which avoid using balun and realize miniaturization and integration [6].…”

A compact low-profile differential filtering microstrip patch antenna with high selectivity and deep rejection using single-layer substrate is proposed. The presented antenna mainly consists of the quasi-H-shaped patch (QHSP) and the meandering quasi-T-shaped resonator (QTSR) which is composed of two open-end meandering arms in opposite direction and an inset coupling structure. To the best of our knowledge, a novel differential feeding structure is adopted for the first time that a pair of differential inset coupling feeding structures are placed in opposite direction to drive the QHSP with insetting-capacitivecoupling, simultaneously. Its equivalent lumped circuit is further analyzed to study the characteristics. In the point of views of filter and antenna design, the meandering QTSR not only acts as the first stage of resonator, but also a feed structure, and the QHSP can be treated as the last order of resonator as well as the radiator. A prototype of the proposed antenna is designed, analyzed, simulated and measured. Two controllable radiation nulls (RNs) locate at the both sides of the passband, a sharp skirt selectivity with the sideband roll-off rates of 667/182 dB/GHz and out-of-band suppressions of -40.1/-39 dB in lower and upper stopbands are achieved, respectively. The measured flat realized gain can be obtained in the passband with the average gain more than 6 dBi and the low cross-polarization level can be achieved. The dimension of the proposed antenna is only 0.361λ 0 ×0.426λ 0 ×0.013λ 0 . Good agreement between the simulated and measured results is obtained, which verifies the proposed antenna with the differential feeding structure has excellent performance only using single layer low profile substrate. The proposed antenna is a good candidate for WLAN and power harvest application.
