“…These features offer its suitability for the field measurement over high frequencies. Though very few literature [7] is found on microstrip patch antennas as EMI sensors, the use of such antennas for field measurement may be a useful alternative to the heavy structures.…”

This work presents an investigation into uncertainty in the far-field measurement using different microstrip patch antennas as electromagnetic interference (EMI) sensors. The measurement is done for vertical and horizontal polarizations. Laboratory measured antenna factor is used. Ideally the strength of radiated field at a point in far-field should be same. It is verified using different EMI sensors. Although there is an average uncertainty of 2-6 dB found in the measurement using rectangular and circular patch antennas in the two polarizations. The uncertainty is introduced in the measurement which is associated with different receiving antennas and determination and application of antenna factor.

In this paper, a new compact dual-polarized microstrip patch antenna is proposed. The patch is of rectangular shape and fed by a gap between the patch edge and a microstrip open end. Gap feeding at the edge of a rectangular patch antenna is proposed for the first time in this paper. This method of feeding occupies a negligible space compared to other feeding methods such as a quarter-wave transformer feeder, an inset feeder, a proximity coupler, and an aperture-coupled feeder. Dual-polarized radiation is realized by feeding a rectangular patch with two orthogonal gaps. First, a single-polarized patch is designed. The impedance matching property of the gap is analyzed using an equivalent circuit. Next, starting from dimensions of the single-polarized patch, a dual-polarized patch antenna is designed by optimizing the patch length and gap width. The designed antenna is fabricated and tested. The fabricated antenna has reflection coefficient less than −10 dB, port isolation greater than 30 dB, over 14.5-15.2 GHz, and a gain of 6.2 dBi at 14.9 GHz.

“…However, existing dual monopole antennas generate a mutual inductance, typical of a radiator with a monopole structure [20][21][22][23][24][25][26]. This has a negative influence on the radiation efficiency of the antenna, as it increases the reactance [27][28][29][30][31].…”

Abstract-In this article, a design for wideband dual-frequency folded dual monopole antenna is presented. By the proper choice of the dimensions of the Y-shape patch and the gap distance for the feeding structure, an additional resonant mode and wide impedance matching can be realized. Both simulated and experimental results, such as antenna impedance bandwidth, antenna radiation characteristic, and antenna gain have been presented and discussed. The lower impedance bandwidth covers from 8.78 GHz to 9.05 GHz, and the upper impedance bandwidth covers from 11.64 GHz to 12.01 GHz.
