“…Against them, the proposed DP configuration yields polarization and BW tuning by changing the individual stub dimensions for the individual patch modes. Configurations presented in [27][28][29][30] offer nearly the same BW as compared with the proposed design. However, they provide a single polarized response with a larger patch size.…”

The design of a compact Pi-shape microstrip antenna for dual-polarized wideband response is proposed. The Pi-shape geometry is realized by modifying a compact C-shape patch. The two stubs placed on the Pi-shape patch edge optimize the spacing in between the higher order TM 20 and TM 30 resonant modes with respect to the fundamental TM 10 mode which yield a bandwidth of more than 430 MHz (> 35%). On an air suspended substrate, the antenna exhibits broadside gain of more than 5 dBi over the impedance bandwidth. The orthogonal surface current variations across the TM 10 , TM 20 , and TM 30 modes realize polarization agility satisfying the requirements of GSM900/navigation satellite applications/ISM900. With respect to the band start frequency, the proposed configuration offers 11% reduction as compared with the equivalent rectangular microstrip antenna. Further, by defining the resonant length at each of the Pi-shape patch modes, the formulation for their resonant frequency is proposed. The Pi-shape antennas redesigned using them at the given fundamental mode frequency yield similar dual polarized wideband responses offering bandwidth of > 35%.

“…However, all modes except TM 01 have a significant magnitude of side lobe which can be reduced if slots are placed at certain E-field null positions. For a patch extending from 0 to L which is operating in the TM 05 mode, the slot positions are 0.3 and 0.7 L. 24 Therefore as we wish to obtain low side lobe broadside radiation in the TM 05 mode, we place two slots at the specified locations. However, these slots also result in broadside radiation in the TM 04 mode.…”

An annular patch antenna operating in both TM 04 and TM 05 modes and conformed to a conical surface is proposed for airborne applications. Dual-slot loading is done to obtain a high gain linearly polarized broadside radiation pattern in both the modes of operation by introduction of additional equivalent magnetic currents. Cavity model analysis of a conical annular patch antenna is carried out and is further extended to obtain the multiport network modeling (MNM) of the dual-slot loaded conical annular patch antenna. Additional control over directivity and side lobe level can be achieved by variation in ratio of slot lengths. The effect of curvature on the antenna performance is studied using MNM. The antenna produces a gain of 9.26 and 8.83 dBi in X-band frequencies of 9.838 and 10.323 GHz respectively.

“…A slot cut technique increases the MSA BW without increasing the patch size. Here, different slot shapes like, U‐slot, rectangular slot, and their modified variations have been used 21–31 . A single layer single‐patch slot cut wideband MSAs are relatively complex in design as compared with the simpler multi‐resonator gap‐coupled MSAs.…”

Wideband designs of proximity fed isosceles triangular microstrip antennas gap‐coupled with pairs of sectoral patches are proposed. Bandwidth enhancement is due to the gap‐coupling between the fundamental modes of the fed and parasitic patches, which are placed in an empty area around the fed patch. Amongst all the variations, 80° isosceles triangular microstrip antenna gap‐coupled with three pairs of sectoral patches yields maximum bandwidth of around 800 MHz (~55%) with a peak gain of 9 dBi. Furthermore, the resonance frequency formulation against varying angles in isosceles triangular microstrip antenna and subsequent design methodology is presented. This is useful in re‐designing the similar wideband design for any angle in the isosceles triangular patch and at the specific fundamental mode frequency.
