In this work, tri resonance multi slot microstrip patch antenna which operates at three center frequencies of 11 GHz, 11.9 GHz, 15.7 GHz is designed and simulated. As a commercial simulation tool, Sonnet Suites, a planar 3D electromagnetic simulator was used. Details of the simulation results are presented and discussed. As a result, an input match of -6.88 dB at the resonance frequency of 11 GHz, an input match of -37.12 dB at the resonance frequency of 11.9 GHz, an input match of -29.49 dB at the resonance frequency of 15.7 GHz were observed. The gain was observed as 8.25 dB at 11 GHz and 4.82 dB at 11.9 GHz. Also, the gain was observed as 7.07 dB at 15.7 GHz. The patch has several symmetric slots and it’s well known that slots change the current distribution of the patch antenna.

A novel compact patch antenna with Defected Ground structure (DGS) operating for Wireless applications is proposed and investigated. This proposed antenna generates four separate resonances to cover 3.271 GHz (WiMax), 4.92 GHz (WiFi), 6.35 GHz (Space applications), and 11.04 GHz (Fixed Satellite applications) while maintaining overall compact size of 32 × 32 × 1.6 mm 3 using an FR-4 substrate commonly available with a permittivity of ε r = 4.4. The proposed microstrip patch antenna (MSPA) consists of a square radiator in which a periodic slot is etched out along with square defects on ground surface and a microstrip feed line. The periodic slot with DGS modifies the total current path thereby making the antenna operate at five useful bands. Structure displays the impedance bandwidth of 8.

“…To improve the bandwidth of antenna different defected ground planes are reported by several authors [11] [12]. Further, using different shapes of DGS or slots in ground and patch can also enhance the bandwidth, gain and directivity [13]- [15]. The comparative performance of different wideband antennas is reported by several authors with impedance bandwidth and gain characteristics due to their compact structure using DGS [16]- [19].…”

A compact circular ring antenna with defected ground structure (DGS) has been design for Ultra-Wide Band (UWB) applications. Initially, a circular patch antenna is design by introducing a rectangular DGS structure. Further, slot has been inserted in circular patch to improve the impedance bandwidth. The proposed design covers the frequency range of 2.4-10.4GHz below -10dB. Proposed antenna has design and fabricated on FR -4 substrate having 1.5mm, 4.3 thickness and dielectric constant, respectively. The performance of the designed antenna is analyzing with optimized dimensions in terms of return loss, VSWR, radiation pattern, gain characteristics, group delay and surface current distributions. Further, performance analysis of the proposed antenna has also been compared with existing suggested antennas in literature with compact in size. The fabricated antenna shows a good result with simulations software.
