Rings, Stubs and Rototillers - Radio World
2002年12月3日 · A variation on the ring radiator is the ring-stub. The horizontally-polarized radiation is produced by the ring portion of the radiating element. The popular Shively 6814 is an example of a ring-stub design. Slants and panels. The …
Circularly polarized stub-loaded annular ring patch antenna for …
2023年8月1日 · A stub loaded circularly polarized annular ring patch antenna operating in the 3–5 GHz band, intended for use in 2×2 MIMO satellite systems is proposed. The antenna achieves circular polarization and mutual coupling through the integration of a half-wavelength hairpin stub loaded patch and diagonal slots above these patches.

This is a circularly polarized antenna. Designed for 3 kW for a single bay. Ring Stub Design; Pressurization Needed; Pattern Study available with custom mounts; Easy install and assembly on site; Includes Fine Matching Transformer; Performance Specifications: Polarization: Right Circular; VSWR: Under 1.08 :1 ± 100 kHz
In this paper, a microstrip line fed rectangular ring monopole antenna loaded with a slit is proposed for tri-band WLAN/Wi-MAX operations. The slit is embedded into the rectangular ring patch to realize dual-band operations. Further, to achieve tri-band operation, parasitically coupled stub of quarter wavelength is placed on the partial ground.
Wideband Ring-Monopole Flexible Antenna with Stub for …
2022年9月28日 · In this paper, we propose a wideband flexible ring monopole antenna. A CPW (coplanar waveguide) feeding structure is used in which the signal line and ground are on the same plane. The CPW feeding structure is suitable for flexible antennas because the antenna is thinner and easier to bend.
Stub Loaded Semi-annular Ring Microstrip Antenna for
2019年11月17日 · A multiband dual-polarized configuration using stub loaded semi-annular ring-shaped microstrip antenna is proposed. The connected stub tunes the frequencies of higher-order mode TM 20 and TM 40 relating to fundamental mode TM 10 and third mode TM 30 that yields multiband response.
Design of multiband stub loaded oval ring patch antenna with …
This paper proposes a stub loaded oval ring patch antenna mounted on a serpentine shaped EBG ground. The patch antenna possesses dimensions of $18\times 18\times 0.8\text{mm}^{3}$ . Miniaturization of 89.1% is achieved with the proposed antenna structure.
Ring with Rectangular StubMIMO Antenna for RFID Applications
This paper presents a MIMO antenna using two elements in the shape of a ring with a rectangular stub for RFID applications. The proposed MIMO antenna is multiband with center frequencies at 2.45GHz, 3.5GHz, and 5.4GHz. Mutual coupling between the two antenna elements is improved by placing a U-type resonator.
