Design and analysis of monopole patch antenna with triple band rejection characteristics

Abstract

In this paper, a slot loaded ultra wideband monopole patch antenna with triple band‐notched characteristic has been presented. The antenna consists of rectangular patch with three modified inverted U‐shaped slots to create three notches at Wi‐MAX (3.3–3.6 GHz), C‐band (3.7–4.2 GHz), and WLAN (5.15–5.85 GHz) frequencies. Lumped‐element equivalent circuit model and current distribution curves have been used to explain the triple band‐rejection characteristics of the designed antenna. The proposed triple notch structure has been fabricated and tested against simulated data. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:138–142, 2017

Design, Development and Analysis of Aperture monopole patch Antenna for UWB Communication with multiple notched capabilities

“…In [14] triple notch characteristics has been arise at WLAN,WiMAX, and satellite service band by introducing c-shaped slot in radiator, CSRR in ground plane and inverted U slot in middle radiator near to fed line respectively. In [15][16][17][18][19] an improved technique has taken for band rejection purpose but due to this some complexity has also arrived, some are lacking in gain too. A detailed compared table for our work to those reported work is shown in the preceding section.…”

“…To reject WLAN and WiMAX two thin bent slots in radiator [8], two L-shaped conductor baked plane in ground [9], two modified complementary inverted U-shaped in radiator [10] and combination of U and inverted U shape in patch [11] are used in literature. Now a day's triple notching UWB antennas are being investigated as they are capable to discard three different interfering bands from UWB frequency range [12][13][14][15][16][17][18].In [12] a good attempt to reject different interfering unlicensed band like WiMAX, WLAN and downlink-X band has proposed but lacking in the proper bands of rejection (more wider). In [13] some arrangement has been applied to reject sharper rejections among WLAN lower and upper frequencies, but care has not been taken for WiMAX range as they are wider than required also having bigger and complex size.…”

Investigation of a defected ground structure inspired wideband printed monopole mobile antenna using characteristics mode analysis

“…This makes the antenna design more complex and requires precision, since antenna placement and its orientation can severely affect the signal diversity. Hence, in our study, a printed monopole antenna 18 with defected ground structures (DGS) 19–21 is utilized and expected to provide effective broadband matching, acceptable gain, and consistent radiation pattern in the designated operating bands. To achieve such type of trade‐offs from application point of view, a thorough analysis with its understanding to certain antenna parameters that affect the system performance is required, especially dealing with the compact multi‐resonant mobile antennas, that is, getting through the physics into simulation 22 .…”

Gain enhancement of a quad notched CPW fed UWB antenna

“…One of the possible solutions is to design of a UWB antenna with integrated band notch characteristics. Different design procedure such as the use of tuning stub, parasitic stub, slots on the radiator, slots in the ground plane, resonating structure in the feed line, split ring resonator has been proposed by the researchers to achieve the band notch. Slots on the radiating ground plane or the radiating patch do not require any extra space thus maintaining the antenna compact.…”
