Due to the fast development of wireless communication technology, reconfigurable
antennas with multimode and cognitive radio operation in modern wireless applications with …

This paper presents a critical review of modern 4G, 4G/5G, and 5G antennas, which employ
PIN diodes and Varactors for polarization or frequency reconfiguration. For the reviewed 4G …

This study proposes a compact design of frequency-reconfigurable antenna array for fifth
generation (5G) cellular networks. Eight compact discrete-fed slot antennas are placed on …

This study presents the design of switching techniques for dual‐notched ultra‐wideband
antenna. The dual band‐notched frequencies are achieved by using switched defected …

In this article, a compact microstrip‐fed slot antenna with circular polarization characteristic
for 5–6 GHz wireless local area network (WLAN) systems is presented. The proposed …

In this paper, a novel design of dual-band monopole antenna for radio frequency
identification (RFID) systems is proposed. The proposed antenna is designed to operate at …

In this article, a novel small monopole antenna with dual band‐notched characteristic for
ultrawideband applications is proposed. The proposed antenna consists of circular‐disc …

In this paper, a different method for designing a novel and compact microstrip-fed slot
antenna with band-notched characteristic for UWB application is proposed. In the proposed …

This article discusses the use of compact ultrawideband (UWB) microstrip monopole
antenna with reconfigurable band rejection in cognitive radio. Frequency characteristics of …

A new design of multi-resonance small slot antenna with band-notched function for UWB
applications is proposed. The proposed slot antenna consists of a square radiating stub and …
