In this paper, a 15* 80 sized antenna is designed over a paper substrate to test its flexible properties. The proposed antenna feed by a grounded coplanar waveguide(GCPW) is stimulated and the measured results show the operating Dual Band of the antenna cover(3.34-3.62 GHz) and (5.92-6.24 GHz) with the reflection coefficient |S11|< -15dB.These frequency bands operate over SHF bands and hence supports Fixed Mobile Communication and WLAN applications.

Background: The Planar Inverted-F Antenna (PIFA) is most widely used for wireless communication applications due to its unique properties as low Specific Absorption Rate, low profile geometry and easy fabrication. In literature a number of multiband PIFA designs are available that support various wireless applications in mobile communication, satellite communication and radio frequency field. Methods: In this paper, a miniature sized planar inverted-F antenna has been proposed for dual-band operation. The antenna consists of an asymmetrical pentagonal shaped patch over an FR4 substrate. The overall antenna dimension is 10 × 10 × 3 mm3 and resonates at 5.7 GHz frequency. A modification is done in the patch structure by introducing an asymmetrical pentagon slot. Results: The proposed pentagonal antenna resonates at 5.7 GHz frequency. Further, modified antenna resonates at two bands. The lower band resonates at 5 GHz and having a bandwidth of 1.5 GHz. This band corresponds to C-band, which is suitable for satellite communication. The upper band is at 7.9 GHz with a bandwidth of 500 MHz. Performance parameters such as return loss, VSWR, input impedance and radiation pattern are obtained and analysed using ANSYS High- Frequency Structure Simulator. The radiation patterns obtained are directional, which are suitable for mobile communication. Conclusion: The antenna is compact in size and suitable for radar, satellite and vehicular communication.

A novel dual-band planar antenna with a low profile for mobile communication system is proposed in this paper. The antenna is composed of one shorted patch with two radiating notches for low frequency resonance and one square patch for high frequency resonance. The low profile is achieved via the shorting patch, which introduces the parallel electrical field between the reflector and antenna. A step-impedance microstrip line is used to feed the antenna. The coupling between the square patch and microstrip line cancels out the inductance of shorting probe, which increases the working bandwidth of proposed antenna. A prototype with a low profile of 0.0286λ is fabricated and measured. The antenna achieves dual impedance bandwidths of 1.6% for the low frequency band and 60% for the high frequency band, covering the frequency range 851–865 MHz and 1.97–3.65 GHz, respectively. The measured results show good agreements with the simulated ones.
