Abstract: This paper introduces a dual-polarized spline-loop antenna element and array. The antenna element consists of two pairs of cross spline-ring dipoles, each with four thin metal strips ...

Abstract: The acoustically excited antennas based on the piezo-electric effect (PE) have been shown to reduce the size of the long wave communication system transmitter (Tx) to 10 −4 of the wavelength ...
