Abstract-In this paper, a compact, planar ultrawideband (UWB) monopole microstrip antenna is proposed which offers dual band notch characteristics with enhanced rejection at frequency bands centered at 3.4 GHz and 5.5 GHz. To realize enhanced band notched characteristics at 3.4 GHz, a pair of filters is incorporated which includes an inverted 'L' shaped slot and a twisted 'J' shaped slot in the patch element. Another pair of filters comprises of a spur line filter in the feed line and 'U' shaped slot in the patch are used to get a strong frequency band rejection centered at 5.5 GHz.Step by step development of the antenna with its analysis in frequency and time domain is presented. The prototype is fabricated and the measured results are presented which are in close similarity to the simulated results.

A novel technique for radar cross section (RCS) reduction of printed antennas is proposed in this paper. After analyzing the current distribution on the surface of the printed antenna in working state, the region with small current amplitude is decreased in area. Then the RCS of the antenna would be reduced without effects on the radiation performance. Based on a printed UWB antenna, a modified antenna is presented as an example to validate the novel technique of radar cross section reduction (RCSR). Radiation and scattering characteristics of the modified and reference antennas are simulated and experimentally verified. The results show that the modified antenna has lower RCS than the reference antenna in the whole frequency band while maintaining the same radiation performances, which illuminates that the proposed technique is a good candidate for printed antennas with a requirement of RCS control.

“…This type of monopole antenna is not easy to integrate into handset or mobile terminal devices [1]. Wideband technology is more attractive in wireless communication, and it has been widely used in wireless applications especially in the cognitive radio systems [3]. Antennas with wideband systems including ultra-wideband (UWB) antennas transmit narrow pulses instead of continuous wave for sending information.…”

In this article, a novel compact SEBG structure with rectangular slotted microstrip patch antenna has been proposed for cellular applications. The parameters of the EBG structure (spacing, width, length, and number of the micro strip lines) and the thickness of the substrate were optimized using CST Microwave Studio to obtain the maximum gain and bandwidth. Although the EBG structure reduced the surface wave, the bandwidth enhancement was due mainly to the coupling between the patch and the SEBG structure. To validate the proposed concept, experimental results have been presented, showing that the bandwidth is 93.2% and 11.75% increased than the patch at lower and higher resonant frequency, respectively, with the new substrate.
