A circularly polarized CP circular patch microstrip antenna with a cross slot using an L-shaped probe fed by a microstrip line is designed and measured. With the single L-probe, the impedance bandwidth, the axial-ratio bandwidth, and the gain bandwidth are 27, ( ) 3.47, and 26%, respecti¨ely, for th

✦ Synopsis
The L-shaped probe is shown to be an excellent feed for the thick circular patch antenna. The substrate used is a foam layer of thickness about 10% of the operating wa¨elength. An impedance bandwidth of 24% and an a¨erage gain of 7.5 dBi are achie¨ed.

## Abstract This paper presents a wideband patch antenna fed by a modified L probe. The antenna has impedance bandwidth of 21% (SWR < 2) and cross polarization level of less than −15 dB across the operating bandwidth. The antenna has a gain of 8.5 dBi. Both simulated and experimental results are pr
## Abstract A novel design of a microstrip patch antenna incorporated by two orthogonal L‐shaped switchable slots is proposed to achieve circular polarization. Two pin diodes are inserted into these L‐shaped slots and by making these two pin diodes ON and OFF the antenna can radiate with either rig
## Abstract A two‐element hexagonal‐shape stacked‐patch antenna array fed by an L‐shaped probe is designed and measured. Experimental results show that the array achieves an impedance bandwidth of 34% (SWR < 1.5)/44% (SWR < 2) and a gain of 11.5 dBi. The far‐field radiation pattern is stable across
## Abstract Simple folded‐patch antennas fed by an L‐shape probe are designed and studied experimentally. This simple antenna structure with thick air substrate attains a projection‐length reduction of about 30% with reference to the conventional half‐wave patch antenna. This antenna attains an imp
## Abstract Experimental results for an __L__‐probe‐fed shorted semicircular patch antenna are presented. Using a foam layer thickness ∼0.12λ~0~ as a supported substrate, an impedance bandwidth of 57% (SWR≤2) and a gain of over 4.0 dBi in the majority of the wide bandwidth have been obtained. The f
