Ultra-wideband (UWB)
Abstract:
In this paper, we proposed an integrated ultra-wideband (UWB) and narrowband (NB) antenna for cognitive radio applications. The UWB antenna was achieved using a fat monopole with a microstrip type feed-line. The antenna can be reconfigured to a switchable NB antenna by the use of cascaded complementary split ring resonators within the feed-line. The reconfigurability was based on a frequency-switchable filter embedded in the feed-line. Simulations and measurements demonstrated that the UWB mode operated from 2 to 10 GHz, while being able to switch to multiple NB frequencies. � 2013 IEEE.

A dual-band, low profile, high gain, and low specific absorption rate (SAR) triangular slotted monopole antenna backed with a artificial magnetic conductor (AMC) array is presented for wireless body area network (WBAN) ...
This paper presents an efficient approach for the evaluation of the RCS of cross- patch antennas on ferrite substrates. The direction of the do magnetization of the ferrite is assumed arbitrarily in theta and phi. The ...
