✦ Synopsis

Figure 3 Measured return loss for dual-frequency operation; s r 4.4, h s 1.6 mm, w s 1 mm, d s 16 mm, l s 14 mm y Figure 4 Measured E-plane and H-plane radiation patterns for the dual-frequency operation with l s 12 mm. Other parameters are x given in Figure 3

3. Conclusions

A single-feed, reduced-size circular microstrip antenna with dual-frequency operation has been implemented. The two operating frequencies are with perpendicular polarization planes, and are significantly lowered by insetting slits at the boundary of the circular patch. This dual-frequency design can also be excited using a single probe feed for a frequency ratio up to about 1.5, and good cross-polarization radiation for the two operating frequencies is also observed.

## Abstract A CW‐mode optically controlled microwave switch (CW‐mode OMS) on a coplanar waveguide (CPW) for both a standard and a new design with carrier‐confinement structure is investigated. We experimentally show that it may not be possible to obtain less than 7 dB of insertion loss with the sta

## Abstract A steerable antenna using a movable dielectric phase shifter is designed and developed. The change of the effective dielectric constant at different dielectric slab positions on a CPW is used as the phase shifter. The impedance matching and desired phase shift conditions are satisfied a

In this paper, a new approach to optimally design a phase shifter consisting of a periodic array of ferroelectric-based tunable planar interdigital capacitors (IDCs) is presented. Spiral slots in the proposed configuration reduces the overall size and improves the performance by 30%.
