Dual-frequency planar antennas can substitute large bandwidth patch antennas, where there is a requirement for large bandwidth to cover two separate transmit receive bands. In this paper a novel single-feed, single layer, double-band, compact short loaded patch antenna is studied theoretically and experimentally. Besides the compactness, this design provides, dual frequency operation with a small frequency ratio of 1.3 between the two resonant bands. Various radiation characteristics are simulated as well as experimentally studied and good concurrence is observed between the simulated and measured results

Antenna design has become as established field of research in recent years. The most important feature of MPA is low cost, low profile and single layer configuration. The frequency band at which the patch antenna operates is 12-1GHz and antenna array are fielded by Microstrip field line incorporated with 50 Ω impedance. In order to achieve enhancement in gain, directivity, bandwidth and return loss Quarter wave transformer and power divider are used. Microstrip patch antenna, employed with highly reflective properties   is presented with the results of modeling, design and simulation. To illustrate this techniques a KU band 2×1, 4×1, 8×1antenna array integrated with series corporate feeding network are designed and simulated. The maximum gain of14.56dB at 10 GHz, the impedance beam width is 86.72% and 99% efficiency is arrived using this technique. Maximum radiation pattern is achieved by using low dielectric substrate of RT-DURROID. The design is verified using HFSS software, used to simulate the antenna array.

AbstractA high-gain lens antenna employing single-layer focusing metasurface (MS) is proposed in this article. The single-layer element achieves a 360° transmission phase range with a transmission magnitude better than 0.9. And the focusing MS consists of 169 elements was designed by utilizing the technique of varying rotation angle to compensate the phase delay. Thus, a lens antenna is constructed by placing a circularly polarized (CP) patch antenna at the focal point of the MS. The fabricated lens antenna demonstrates a good performance of 4.6 % 3-dB axial ratio bandwidth and 6 % 1-dB gain bandwidth, respectively. Moreover, the maximum gain is 18.3 dBic at 15 GHz, which is enhanced by 11.4 dBic compared with the patch antenna. Due to the single-layer structure, this design has a low profile and easy fabrication process compared with the conventional designs, making it an attractive alternative to compact high-gain antenna.
