A low cost dual band offset fed monopole microstrip antenna is proposed in this paper. The suggested antenna is designed using an inexpensive 1.6 mm thick fr-4 substrate of relative permittivity 4.4. The design and analysis of the proposed antenna model have been performed using HFSS software. By inserting a square slot loaded with an inverted metallic structure in the patch and the presence of a partial ground plane, dual band operation with an extremely wide bandwidth for the higher band can be obtained. A comprehensive analysis of characteristics parameters (S11, gain, radiation patterns) including distribution of surface current of the suggested antenna is furnished in this paper. The prototype of the fabricated antenna has an attractive compact dimension of only 22 ( 19 ( 1.6 mm3. The reported measured bandwidths are 800M Hz (4.2-5.0 GHz) and 4200 MHz (8.0-12.2 GHz) for the lower and upper bands, respectively. The measured peak gains across the two operating bands are 3.0 and 4.3 dBi, respectively. The measured results are well accepted and verify the simulated results and hence validates the appropriateness of the design concept. The proposed antenna covers the bandwidth requirements for INSAT (4.4-4.8 GHz) and microwave X-band (8-12 GHz) systems. The compact size, low cost, simple monopole configuration, dual band resonance characteristics, wide bandwidth, good gain, and stable radiation patterns are the advantages of the designed antenna.
