Shunt feed antenna
WebAn antenna for use with a shippinconductive elements shunt fed to an exterior metallic surface of the container. As a result, electromagnetic field energy is radiated or detected by coupling to currents flowing in the surface of the container, rather than by direct coupling to the radio waves themselves. The shunt fed antenna forms a feed system for the mobile … WebShunt (Gamma) Feed It: • A 50’ Tower with a tribander (or equivalent) should resonate close to 1.8 MHz (53.23 - J 106.4 ohms) • Run a wire from the top down, feed with a series capacitor. Think of a Gamma Match arm. • Gamma feed can be slanted from the top down (slant feed). • GOOGLE “Gamma match tower”

A novel compact UWB monopole antenna with an additional narrow band for Wi-Fi applications comprising a metamaterial (MTM) is proposed in this paper. The antenna has a compact size of 27 × 33 mm2 and consists of a V-shaped slot with two …
WebShunt-feeding techniques are used to improve the impedance characteristics of the moderately superdirective normal-mode helical dipole. A novel broadbanding effect is observed, and a VSWR less than 1.65 with respect to 21 \Omega over a 3 percent bandwidth is obtained with no degradation of radiation pattern.
