Global Positioning System (GPS) antennas installed at fixed site infrastructure are susceptible to interference incident along the direction of the horizon. In this paper, a series of quadrifilar helical antennas are presented for the application of

A low cost dual-band shorted annular ring patch antenna is presented for the application of GNSS reception with interference rejection at the horizon. It is shown that the antenna can achieve circular polarization with a single feed pin using two shu

In this paper, the performance properties of several fundamental small-antenna designs are compared as a function of overall length and size (ka), where the antennas operate at or very near the same frequency. The objective of this work is to determi

We have performed CW measurements on the metamaterial wedge providing detailed insight into its behavior and operating bandwidth limitations. Measurements with a narrowband modulated signal have demonstrated that negative refraction exists with a pra

The phenomenon of negative refraction in a Metamaterial wedge is known to be relatively narrowband. Here, we first experimentally estimate the negative refraction bandwidth of a Metamaterial wedge using a slab and a series of CW measurements. We subs
