A new antenna, the planar inverted cone antenna (PICA), provides ultrawideband (UWB)
performance with a radiation pattern similar to monopole disk antennas , but is smaller in size. …

Broadband wireless communications require wideband antennas to support large number of
users and higher data rates. Desirable features of a wideband antenna are low-profile, dual…

A report on an investigation of spherical, disc, and half-disc antennas in the frequency and
time domains with the objective of developing small planar versions of the antennas. These …

We apply the concept of electromagnetic invisibility/cloaking to improve the radiation properties
and decouple two tightly spaced and interleaved phased linear antenna arrays of strip …

In this letter, we endeavor to curb the adverse effects of mutual coupling between two-slot
antennas (operating at C-band frequencies), situated at a subwavelength separation. The …

The rate of wireless data transmission is limited by the antenna bandwidth. We present an
efficient technique to realize a high-rate direct binary FSK modulation by using the transient …

An electromagnetic cloaking approach is employed with the intention to curb the destructive
effects of mutual interference for rectangular and circularly shaped patch antennas situated …

A new UWB antenna, the sail-boat antenna, is proposed that provides a stop-band notch in
the 5-GHz WLAN band. The CPW-fed sail-boat antenna offers a compact planar structure. …

We have proposed an effective metasurface design to accomplish the cloaking of equilateral
patch antennas and their array configuration. As such, we have exploited the concept of …

Many disc antennas have been proposed for ultra-wideband (UWB) applications, but they
suffer from the disadvantages of requiring a large ground plane and a complicated feed …
