This paper describes a compact, self-complementary square-spiral antenna on a GaAs substrate with a broadside high-directivity (ϳ29 dB) frequency-independent pattern when coupled through a silicon hyperhemisphere. The driving-point resistance undulates between ϳ100 and 300⍀ from 200 GHz to 1 THz-muc

Abstract
A folded Hilbert curve fractal antenna (fHCFA) which produces end‐fire radiation at the S‐band and broadside radiation at the Ku‐band without switches is presented. The measured gains/bandwidths were 1.2 dBi/10 MHz and 5.4 dBi/500 MHz at 2.3 GHz (S‐band) and 16.8 GHz (Ku‐band), respectively. This work offers a compact antenna design as a candidate for robotic applications in future NASA planetary exploration missions. © 2006 Wiley Periodicals, Inc.

## Abstract A new type of artifical metallic electromagnetic structure, high impedance electromagnetic surface (HIS), has been developed that is characterized by having high surface impedance. In this paper, the HIS is used as the antenna ground plane to suppress the propagation of surface waves an
## Abstract Partially reflective surface antenna (PRSA) contains a highly reflective sheet and a perfect conductor (or ground plane) separated by a half wavelength. Usually, the reflective sheet is constructed by etching uniformly spaced patch elements on a supporting dielectric. In this article, a
