TLDR
In this article, a coplanar waveguide-fed ultra-wideband (UWB) antenna with a simple radiating patch and a slotted radiating patches based on a DMS structure is proposed.Abstract:
The research presents a compact antenna consisting of a simple radiating patch and a slotted radiating patch based on a DMS structure. It is required to have a tunable notched behavior in the antenna to avoid interference of Wi-Fi, Wi-MAX, WLAN frequency as it comes under ultra-wideband (UWB) designated band. Also, a coplanar waveguide (CPW)-fed will be used for UWB monopole antenna in the patch. A DGS structure is used for the notch characteristic to fit the entire antenna into a compact area. The measured results for the proposed antenna provide a notch at 2.4 GHz. The designed CPW ultra-wideband antenna sized of 30 × 30 × 0.8 mm3, operates for the frequency band between 1 and 10 GHz.read more

Design of reconfigurable slot antennas
TL;DR: In this article, a single-fed resonant slot loaded with a series of PIN diode switches constitutes the fundamental structure of the antenna and the antenna tuning is realized by changing its effective electrical length, which is controlled by the bias voltages of the solid state shunt switches along the slot antenna.

Broadband CPW-fed square slot antennas with a widened tuning stub
TL;DR: By using a coplanar waveguide (CPW) feed with a widened tuning stub, a square slot antenna for broadband operation is presented in this paper, where the authors show that the impedance matching for the proposed antenna strongly depends on the location of the tuning stub in the square slot, and the impedance bandwidth is mainly determined by the width and length of the tuned stub.
