A novel, compact and dual polarized ring Sectoral Monopole Antenna (RSMA) with defected ground is presented for Ultra Wide Band (UWB) applications. Present structure has been derived from the circular monopole antenna to accomplish dual polarization characteristics without much change in the impedance band width, radiation pattern (quasi Omni-directional) and other antenna characteristics. Proposed...
A novel bow-tie slotted substrate integrated waveguide (SIW), leaky wave antenna is proposed and investigated. This antenna works in the TE10 mode. Proposed antenna leads to more intense electric field and better coupling of E-field in adjacent slots, which results in more uniform spectral behavior in comparison with transverse slot leaky wave antenna. In addition to this proposed antenna gives improved...
A simple and compact planar printed monopole antenna for ultra wideband application is presented. The proposed antenna comprising of bevel slots in the lower parts of the antenna with annular ring slot. Partial ground plane has been used to enhance the impedance bandwidth. The simulated results show that the proposed antenna exhibits UWB for 2.7 GHz to 11.22 GHz with −10dB return loss and VSWR <...
In this paper design and optimization of low cost, wideband, compact printed rectangular ultra wide band (UWB) antenna at lower edge frequency is proposed and investigated. Antenna is fed by microstrip line. Antenna is having a rectangular patch and modified ground structure. Bandwidth enhancement is obtained by modifying the destructive ground plane structure (DGS). Antenna has been simulated using...
Broadband microstrip antenna is more commonly realized by cutting the slot at an appropriate position inside the patch which is fabricated on lower dielectric constant thicker substrate. In this paper, a new 2700 sectoral microstrip antenna is proposed. The 2700 sectoral patch, derived from conventional circular microstrip antenna, has an additional mode below the resonance frequency of fundamental...
Broadband antennas that are small in size and simple in structure are typically demanded for such applications. In this paper, we present two prototypes of microstripline fed capacitively coupled microstrip antennas. First prototype consists of microstripline fed capacitively coupled for broadband antenna at 2.5 GHz. This bandwidth is 11 times greater than conventional microstrip antenna (MSA). Here,...
A novel compact microstrip line fed diamond shaped monopole antenna for Ultra Wideband (UWB) applications is proposed. The antenna structure consists of a diamond shaped radiating patch and a semicircular like ground plane. The radiating patch is derived from a conventional rectangular patch antenna. The simulated results show that the impedance bandwidth (VSWR ≤ 2) of the proposed antenna ranges...
Using the proximity feeding technique, broadband microstrip antenna has been realized by fabricating the patch on lower dielectric constant thicker substrate. The antenna bandwidth and its gain are also increased by using multiresonator gap-coupled configurations. In this paper, broadband proximity fed pair of rectangular slot cut rectangular microstrip antenna is proposed. An analysis to study the...
